Summary of changes from v2.6.6-rc2 to v2.6.6-rc3
============================================


	Can not mount from cifs vfs client built with gcc 3.3.1 due to compiler optimization of unsafe global variable. Remove unsafe global variable.


	Fix problem reconnecting additional mounts to the same server after
	session failure.


	Fix invalid dentry when race in mkdir between two clients


	fix oops in send_sig on unmount of cifs vfs due to sending signal to demultiplex thread after it has exited.  
	Do not treat invalid handle warning in response to oplock break (of file that is now closed) as an error.


	Fix EIO caused by network timeouts on changing file size.  
	To avoid spurious oplock breaks from server, in the case
	of inodes that we already have open, avoid doing path
	based setting of file size if we can do it by handle.
	This keeps our caching token (oplock) and avoids
	timeouts when the local oplock break takes longer to flush
	writebehind data than the SMB timeout for the SetPathInfo 
	request would allow


	fix to not retime out the same session twice since it can invalidate the newly reestablished session unnecessarily


	Do not return buffer if request has already timed out.


	move bad smb session retry to correct location, up one level in cifs vfs code


	fix endian bug in lockingX and add retry on EAGAIN


	have to reconnect open files safely, one at a time, as needed


	finish off move from reopening all files on reconnection (which takes too long under heavy stress) to reopen file as needed after reconnection to server.


	correct retry on remaining handles based calls


	Fix compile error


	Missing soft vs. hard retry mount option


	Do not grab i_sem (already taken in filemap.c across commit write calls) during reopen of invalidated file handle.


	Fix oops in mount error path when unload_nls called with bad pointer.


	Avoid smb data corruption under heavy stress


	missing message on timed out requests


	rcvtimeout set improperly for some cifs servers


	invalidate locally cached pages when server breaks oplock.  Do not loop reconnecting for servers that drop tcp session rather than sending smb negprot response


	Oops on reopen files when dentry already freed


	invalidate cached pages when last local instance closed so we do
	not use stale data while someone may be modifying the file on the
	server.


	fix double incrementing of transaction counter


	Fix check of filldir return code during readdir to avoid incomplete search results displayed on very large directories. Fix cleanup of proc entries.  Add config parm to allow disabling negotiating Linux extensions 


	allow disabling cifs Linux extensions via proc


	Fix an incorrect mapping of open flags to cifs open disposition.  Fix blocking byte range locks.  These fix breakages that were notice running lock tests 1 and 7 of the connectathon posix file api tests


	set byte range locktimeouts properly


	fix cifs readme


	gracefully exit on failed mounts to win98 (which closes tcp session rather than erroring on smb protocol negotiation)


	fix failed mounts to win98 part II


	Fix global kernel name space pollution


	Check return on failed dentry allocation.  Suggested by Randy Dunlap


	Allow null password string pointer and passwords longer than 16 bytes


	finish handling commas in passwords


	finish off mount parm sep override


	Fix caching problem with multiply open files from different clients


	Relax requested CIFS permissions on open to simply request GENERIC_READ and GENERIC_WRITE (instead of GENERIC_ALL which
	can unnecessarily conflict with share permissions by asking implicitly for take ownership and other unneeded flags)


	fix remoting caching part 2


	remove spurious debug messages


	fix problem not connecting to server when port not specified explicitly and port field unitialized


	reset searches properly when filldir fails


	ipv6 enablement for cifs vfs fixes


	Spurious white space and duplicated line cleanup


	NTFS: Set i_generation in VFS inode from seq_no in NTFS inode.


	NTFS: Make ntfs_lookup() NFS export safe, i.e. use d_splice_alias(), etc.


	NTFS: Make it compile...


	improve resume key resetting logic when filldir returns error and filename is in unicode


	allow nosuid mounts


	NTFS: Release 2.1.7 - Enable NFS exporting of mounted NTFS volumes.
	- Implement ntfs_get_parent() and ntfs_get_dentry() as the NTFS specific
	  export operations ->get_parent() and ->get_dentry() respectively.


	NTFS: Add missing return -EOPNOTSUPP; in fs/ntfs/aops.c::ntfs_commit_nonresident_write().


	fix problem with inode revalidation and cache page invalidation


	Fix the exec, suid, dev mount parms to not log warnings when specified


	fix caching data integrity problem


	use safer i_size_write mechanism to update i_size


	NTFS: Fix off by one error in ntfs_get_parent().


	NTFS: Enforce no atime and no dir atime updates at mount/remount time
	as they are not implemented yet anyway.


	PPC32: Add CONFIG_MPC10X_BRIDGE.
	From: Adrian Cox .


	PPC32: In some cases we need to make all pages _PAGE_COHERENT.
	Controll this via the cpu_table flags since it's a requirement
	in some CPU and host bridge combinations.
	From: Adrian Cox 


	fixes for fsx truncate/readahead/writebehind bug


	clean up compiler warnings


	PPC32: Remove an unneeded include in arch/ppc/boot/


	PPC32: Add more useful information to the oops output.


	PPC32: Fix two typos in arch/ppc/boot/
	From: Arthur Othieno 


	Renaming pplus_common.c to hawk_common.c to match gt64260_common.c, etc, plus minor
	cleanups.


	Add missing description about how to specify credentials file


	Invalidate readahead data properly when file closed, but other client changed it on server


	Updating mcpn765 for 2.6


	[SPARC32]: Fix wraparound bug in bitmap allocator


	Merge bk://linux.bkbits.net/linux-2.5
	into linuxbox.(none):/src/linux/ppc/linux-2.5/linux


	Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated
	with server.  This allows files that differ only in case and 
	improves performance of file creation and file open to such servers


	Fix 20 second hang on some deletes of reopened file due to semaphore conflict with vfs_delete on i_sem


	PPC32: Change all #if FOO to #ifdef FOO


	PPC32: Two minor Carolina PReP fixes.
	From Hollis Blanchard .


	PPC32: Assign an interrupt for the VME chip on PReP MVME* boards.
	From Lutz Rossa .


	Updating Force PCore to 2.6


	fix merge problem with 2.6.5 (rename of page struct field list to lru)


	ia64: Quiet another compiler-warning.


	ia64: Drop pci_sal_ext_{read,write}() and instead simply switch to
		extended config-space addresses when needed.  This avoids
		the fragile SAL version testing.


	ia64: When delivering a signal, force byte-order to little-endian.


	[CPUFREQ] Correcting SGTC.  Timer is based upon FSB
	From: Bruno Ducrot 
	
	I think this patch is needed especially if the FSB is around 166MHz or
	200MHz, or else I believe we get instabilities on some K7's motherboard
	powernow capable (it's called Cool'n Quiet IIRC).
	                                                                                         
	                                                                                         
	* Deduce fsb from cpu_khz and the max multiplier.  It will be given as kHz now,
	  so that frequency associated to a multiplier will be computate more
	  accurately.  Also, we need it for SGTC (see below).
	* Fix how cpuid is computed in powernow_decode_bios().
	* Be more restrictive for PST.  It may be possible (on desktop shipped with
	  low power Athlon models) that FSB can be changed by dip switchs on
	  motherboard for example.
	* Fix computation for SGTC.  It use the bus timer (and then the bus
	  frequency given by fsb).
	


	[CPUFREQ] don't use speedstep-centrino on unsupported CPUs
	
	From: Dominik Brodowski 
	
	Don't use the ACPI data on CPUs we don't know nothing about.


	[CPUFREQ] powernow-k7 ACPI integration.
	More from Bruno Ducrot.
	
	Warning: it will only half work on the ACER Aspire, though: there is
	no pstate in the DSDT corresponding to the max frequency...
	I'm looking how to handle that correctly, probably at the init stage,
	if the max frequency is not given, then add it to powernow_table.
	
	* Integrate acpi perflib from Dominik.
	* Use acpi if the PST tables are known to be broken (ASUS Aspire match one PST,
	  but give brain damaged values), or use ACPI if no PST found.


	[CPUFREQ] Drop unneeded part of last patch.
	acpi fallback is handled already in the init function.
	


	[CPUFREQ] powernow-k7 needs to init later.
	Due to the possible dependancy on ACPI.


	[CPUFREQ] Remove bogus newline in powernow-k7 driver.


	[CPUFREQ] Add a module parameter to force ACPI to be used.


	Fix misc. minor memory leaks in error paths


	[CPUFREQ] Make powernow-k7 acpi debug output a little less verbose.


	[CPUFREQ] powernow-k7 ACPI->PST values were a factor of 10 off.
	As much as I like the idea of a 13GHz laptop, setting it to 1.3GHz is probably
	for the best for the time being.


	[CPUFREQ] clear defaults before powernow-k7 acpi fallback
	Decoding the legacy tables may have set these values.


	free cifs read buffer on retry


	Fix major page leak in read code caused by extra page_cache_get call


	check permission locally for servers that do not support the CIFS Unix Extensions (allowing file_mode and dir_mode to augment the
	server permission check, by doing local vfs_permission check)


	[CPUFREQ] Not all powernow-K7 BIOS's put the frequency at MAX at POST.


	Remove 64 bit compiler warning


	[PATCH] ia64: fpswa_interface needs to be exported
	
	efivars can be built as a module, but it depends on 'fpswa_interface'
	which is not exported by fpswa.c.  Patch below fixes this problem.


	[CPUFREQ] Fix debug build of powernow-k8
	From Paul Devriendt


	[CPUFREQ] Fix up missing CONFIG_X86_POWERNOW_K8_ACPI 
	We don't need this, we can infer from CONFIG_ACPI_PROCESSOR


	[CPUFREQ] Fix broken cast.
	This breaks on x86-64 with the following warning.
	
	drivers/cpufreq/cpufreq_userspace.c: In function `cpufreq_procctl':
	drivers/cpufreq/cpufreq_userspace.c:170: warning: cast from pointer to integer of different size
	drivers/cpufreq/cpufreq_userspace.c: In function `cpufreq_sysctl':
	drivers/cpufreq/cpufreq_userspace.c:208: warning: cast from pointer to integer of different size


	Remove "badness in remove_proc_entry" warning logged on module unload of cifs


	[SCTP] Avoid the use of constant SCTP_IP_OVERHEAD to determine the 
	max data size in a SCTP packet.
	
	Calculate the overhead based on the socket's protocol family header
	length.


	[SCTP] Cleanup sctp_packet and sctp_outq infrastructure.


	[SCTP] Partial Reliability Extension support.


	[TG3]: Fix typo in TG3_TSO_FW_RODATA_ADDR definition.


	[SCTP] Propagate error from sctp_proc_init. (Olaf Kirch)


	Add in cifs fcntl handling to fix remote dnotify problem


	[ARM] Add find_first_bit and find_next_bit.


	[SPARC64]: Fix 32-bit posix timers.


	Do not cache inode metadata when cache time set to 0 (fix hardlink count caching)


	[SPARC64]: Missing part of posix timers fix.


	[PATCH] Add missing __initdata
	
	One of the stack size optimizations introduced a new static variable in
	a function marked with __init.  But the variable is not marked
	appropriately and so 1k of data is never freed.


	[PATCH] Fix nfsroot option handling
	
	From: Trond Myklebust 
	
	The following patch fixes up a number of bugs in the NFSroot parser
	rewrite from patchset
	trond.myklebust@fys.uio.no|ChangeSet|20040411182341|00938
	
	It also ensures that NFSroot mount options are consistent with the userland
	"mount" program.


	[PATCH] compute_creds race
	
	From: Andy Lutomirski 
	
	Fixes from me, Olaf Dietsche 
	
	In fs/exec.c, compute_creds does:
	
		task_lock(current);
		if (bprm->e_uid != current->uid || bprm->e_gid != current->gid) {
	                 current->mm->dumpable = 0;
	
			if (must_not_trace_exec(current)
			    || atomic_read(¤t->fs->count) > 1
			    || atomic_read(¤t->files->count) > 1
			    || atomic_read(¤t->sighand->count) > 1) {
				if(!capable(CAP_SETUID)) {
					bprm->e_uid = current->uid;
					bprm->e_gid = current->gid;
				}
			}
		}
	
	         current->suid = current->euid = current->fsuid = bprm->e_uid;
	         current->sgid = current->egid = current->fsgid = bprm->e_gid;
	
		task_unlock(current);
	
		security_bprm_compute_creds(bprm);
	
	I assume the task_lock is to prevent another process (on SMP or preempt)
	from ptracing the execing process between the check and the assignment.  If
	that's the concern then the fact that the lock is dropped before the call
	to security_brpm_compute_creds means that, if security_bprm_compute_creds
	does anything interesting, there's a race.
	
	For my (nearly complete) caps patch, I obviously need to fix this.  But I
	think it may be exploitable now.  Suppose there are two processes, A (the
	malicious code) and B (which uses exec).  B starts out unprivileged (A and
	B have, e.g., uid and euid = 500).
	
	1. A ptraces B.
	
	2. B calls exec on some setuid-root program.
	
	3. in cap_bprm_set_security, B sets bprm->cap_permitted to the full
	   set.
	
	4. B gets to compute_creds in exec.c, calls task_lock, and does not
	   change its uid.
	
	5. B calls task_unlock.
	
	6. A detaches from B (on preempt or SMP).
	
	7. B gets to task_lock in cap_bprm_compute_creds, changes its
	   capabilities, and returns from compute_creds into load_elf_binary.
	
	8. load_elf_binary calls create_elf_tables (line 852 in 2.6.5-mm1),
	   which calls cap_bprm_secureexec (through LSM), which returns false (!).
	
	9. exec finishes.
	
	The setuid program is now running with uid=euid=500 but full permitted
	capabilities.  There are two (or three) ways to effectively get local root
	now:
	
	1.  IIRC, linux 2.4 doesn't check capabilities in ptrace, so A could
	   just ptrace B again.
	
	2. LD_PRELOAD.
	
	3.  There are probably programs that will misbehave on their own under
	   these circumstances.
	
	Is there some reason why this is not doable?
	
	The patch renames bprm_compute_creds to bprm_apply_creds and moves all uid
	logic into the hook, where the test and the resulting modification can both
	happen under task_lock().
	
	This way, out-of-tree LSMs will fail to compile instead of malfunctioning. 
	It should also make life easier for LSMs and will certainly make it easier
	for me to finish the cap patch.


	[PATCH] ext3 avoid writing kernel memory to disk
	
	From: Marc-Christian Petersen 
	
	Solar Designer discovered an information leak in the ext3 code of Linux.
	In a worst case an attacker could read sensitive data such as cryptographic
	keys which would otherwise never hit disk media.  Theodore Ts'o developed a
	correction for this.


	[PATCH] Call populate_rootfs later in boot
	
	populate_rootfs() is called rather early - before we've called init_idle().
	
	But populate_rootfs() does file I/O, which involves calls to cond_resched(),
	and downing of semaphores, etc.  If it scheules, the scheduler emits
	scheduling-while-atomic warnings and sometimes oopses.
	
	So run populate_rootfs() later, after the scheduler is all set up.


	[PATCH] remove amd7xx_tco
	
	From: Zwane Mwaikambo 
	
	We've had trouble with this driver, it appears to work but the hardware
	never does the final reboot.  I have yet to come across someone with a
	board which works and don't have personal access to one.  So how about
	scrapping the whole thing.


	[PATCH] lockfs - vfs bits
	
	From: Christoph Hellwig 
	
	These are the generic lockfs bits.  Basically it takes the XFS freezing
	statemachine into the VFS.  It's all behind the kernel-doc documented
	freeze_bdev and thaw_bdev interfaces.
	
	Based on an older patch from Chris Mason.


	[PATCH] lockfs: reiserfs fix
	
	From: Chris Mason 
	
	reiserfs_write_super_lockfs() is supposed to wait for the transaction to
	commit.


	[PATCH] lockfs - xfs bits
	
	From: Christoph Hellwig 
	
	Remove all the code now in the VFS, make XFS's freeze ioctls use the new
	infastructure and reorganize some code.
	
	This code needs some work so the source files shared with 2.4 aren't
	exposed to the new VFS interfaces directly.  You'll get an update once this
	has been discussed with the other XFS developers and is implemented.  Note
	that the current patch works fine and I wouldn't complain if it gets into
	Linus' tree as-is.


	[PATCH] lockfs - dm bits
	
	From: Christoph Hellwig 
	
	This patch makes the device mapper use the new freeze_bdev/thaw_bdev
	interface.  Extracted from Chris Mason's patch.


	[PATCH] i4l: add compat ioctl's for CAPI
	
	From: Marcel Holtmann 
	
	This patch adds the needed compat ioctl's for the CAPI on 64bit platforms.


	[PATCH] selinux: change context_to_sid handling for no-policy case
	
	From: Stephen Smalley 
	
	This patch changes the behavior of security_context_to_sid in the no-policy
	case so that it simply accepts all contexts and maps them to the kernel SID
	rather than rejecting anything other than an initial SID.  The change avoids
	error conditions when using SELinux in permissive/no-policy mode, so that any
	file contexts left on disk from prior use of SELinux with a policy will not
	cause an error when they are looked up and userspace attempts to set contexts
	can succeed.


	[PATCH] selinux: add runtime disable
	
	From: Stephen Smalley 
	
	This patch adds a kernel configuration option that enables writing to a new
	selinuxfs node 'disable' that allows SELinux to be disabled at runtime prior
	to initial policy load.  SELinux will then remain disabled until next boot.
	This option is similar to the selinux=0 boot parameter, but is to support
	runtime disabling of SELinux, e.g.  from /sbin/init, for portability across
	platforms where boot parameters are difficult to employ (based on feedback by
	Jeremy Katz).


	[PATCH] selinux: remove hardcoded policy assumption from get_user_sids() logic
	
	From: Stephen Smalley 
	
	This patch removes a hardcoded policy assumption from the get_user_sids logic
	in the SELinux module that was preventing it from returning contexts that had
	the same type as the caller even if the policy allowed such a transition.  The
	assumption is not valid for all policies, and can be handled via policy
	configuration and userspace rather than hardcoding it in the module logic.


	[PATCH] i810_dma range check
	
	From: Andrea Arcangeli 
	
	Correctly range-check an incoming-from-userspace argument.  Found by the
	Stanford checker.


	[PATCH] i386 hugetlb tlb correction
	
	From: William Lee Irwin III 
	
	i386 does hardware interpretation of pagetables, so pte_clear() can't be
	used on present ptes, as it sets the upper half of the hugepte prior to
	setting the lower half (which includes the valid bit).  i.e.  there is a
	window where having a hugepage mapped at 56GB and doing pte_clear() in
	unmap_hugepage_range() allows other threads of the process to see a
	hugepage at 0 in place of the original hugepage at 56GB.
	
	This patch corrects the situation by using ptep_get_and_clear(), which
	clears the lower word of the pte prior to clearing the upper word.
	
	There is another nasty where huge_page_release() needs to wait for TLB
	flushes before returning the hugepages to the free pool, analogous to the
	issue tlb_remove_page() and tlb_flush_mm() repair.


	[PATCH] loop_set_fd() sendfile check fix
	
	From: Yury Umanets 
	
	I have found small inconsistency in loop_set_fd().  It checks if
	->sendfile() is implemented for passed block device file.  But in fact,
	loop back device driver never calls it.  It uses ->sendfile() from backing
	store file.


	[CPUFREQ] Fix unbalanced try_get_module/put_module
	Spotted by Charles Coffing 


	[CPUFREQ] Remove redundant part of powernow-k7 module parm
	If used as a bootparam, this would've become powernow-k7.powernow_acpi_force which looks silly.


	[CPUFREQ] Make an educated guess at the current P-state in the ACPI driver.
	One big limitation of the ACPI specification is that it's impossible to
	detect the current P-State by reading from ACPI-defined registers. And the
	CPU isn't always at P0 when the system boots. So, try to "guess" the current
	P-State by analyzing cpu_khz.
	
	From Dominik.


	[CPUFREQ] Export an array of acpi driver supported frequencies in sysfs
	From Dominik.


	[CPUFREQ] Fix security hole in proc handler.
	Brad Spengler  found an exploitable bug in the proc handler
	of cpufreq, where a user-supplied unsigned int is cast to a signed int and then
	passed on to copy_[to|from]_user() allowing arbitary amounts of memory to be written
	(root only thankfully), or read (as any user).
	
	The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
	the name CAN-2004-0228 to this issue.


	Revert fb_ioctl "fix" with extreme prejudice.
	
	As Arjan points out, the patch does exactly the opposite
	of what it was claimed to do.

	[PATCH] ide-disk.c: fix for IDE CF card ejection with devfs
	
	From: Pavel Roskin 
	
	If I eject IDE CompactFlash card, I get a stack dump from
	devfs_remove() because ide/host2/bus0/target0/lun0 doesn't exist.
	
	After del_gendisk() is called from idedisk_cleanup() drive->devfs_name refers
	to a non-existent directory and should be erased, so that ide_unregister()
	doesn't try to remove that directory again.


	[PATCH] ide-probe.c: kill duplicate #include
	
	From: Arthur Othieno 


	[PATCH] removal of MOD_{INC,DEC}_USE_COUNT in ide-cs.c
	
	From: Pavel Roskin 
	
	The "ide-cs" module cannot be unloaded because it uses obsolete
	MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros.  In fact, they are not
	needed in ide-cs.c in 2.6 kernels.  The generic PCMCIA code already
	increases use count for every device served by the driver, so it's
	impossible to unload the ide-cs driver while it's in use.
	
	I was told that the removal of IDE interfaces may be unsafe in 2.6
	kernels.  However, MOD_INC_USE_COUNT only prevents removal of the module,
	not the interface.  It's also the first obstacle, albeit a trivial one,
	for anybody debugging those problems (i.e. loading a modified module
	requires "rmmod -f" or reboot to unload the old version).


	[PATCH] PPC64 iSeries virtual ethernet fix
	
	This patch is needed due to other patches that were applied in parallel
	with the inclusion of the iSeries virtual ethernet driver.


	[PATCH] New set of input patches
	
	This  updates the vsxxx driver to it's current version.
	
	Even DEC tablet support (VSXXX-AB) is now tested - it works:)
	You can even hotplug between mouse and digitizer...


	[PATCH] lkkbd: Current version
	
	This updates the lkkbd driver to it's current version.
	
	It also incorporates two patches suggested on LKML (fixing
	some leading whitespace and an unneccessary check).


	[IPV4]: Fix return value on MCAST_MSFILTER error case.


	[NETFILTER]: Missing ip_rt_put in ipt_MASQUERADE.


	[TCP]: Better packing of frto fields into tcp_opt.


	[TCP]: Add sysctl to turn off matrics caching.


	[PATCH] atmel wireless update
	
	Fixes to avoid problems when the driver shares an interrupt. These were
	caused because the ISR cannot determine the status of the chip without
	changing its state and the driver was only disabling the interrupts from
	the card during some critical regions. An interrupt originating from
	another device at the wrong moment could run the ISR and corrupt chip
	state. Fixed by blocking interupts in the processor in critical regions
	and never checking the chip interrupt status before the driver is fully
	up.
	
	
	Added the ability to override the Regulatory Domain stored in ROM. The
	following command achieves this
	
	iwpriv  regdomain 
	
	vaild domains are USA,Canada,Europe,Spain,France,MKK,MKK1,Israel
	
	The current regulatory domain affects which radio channels are available
	for use.
	
	
	Some minor tidying to calibrate busy-wait loops using udelay and remove
	inclusion of obsolete include/linux/802_11.h


	[PATCH] pcmcia netdev ordering fixes
	
	From: Russell King 
	
	This is an *untested* patch (PCMCIA people, please test) to fix
	initialisation ordering issues in these network device drivers.  I don't
	have the hardware to be able to test these changes, although it passes a
	modular build without warnings.
	
	Andrew - it may be worth sticking these in -mm so they get some visibility
	via your tree as well.
	
	Many of these drivers were calling register_netdev() before they had
	completed their initialisation.
	
	In addition, they were calling register_netdev with the
	"DEV_CONFIG_PENDING" flag still set, which prevents hotplug scripts from
	bringing up the interface.
	
	Also, we take care to ensure that link->dev is correctly set - this is used
	to tell the PCMCIA release code if the netdev is currently registered (yes,
	that's probably racy at present, but lets sort one problem at a time.)
	
	I've arranged that all drivers register the netdevice as close as possible
	to the end of their initialisation, copy the net device's name for cardmgr
	to pass to it's network scripts, and then print out whatever information
	the driver wants to.
	
	Finally, a note about ibmtr - it seemed to assume that cardmgr wanted "tr0"
	or "tr1" depending on the base address, and completely ignoring the real
	device which the netdev layer allocated it.  I've assumed that this is
	wrong (since the netdev name is used in printk messages), and changed it to
	behave the same as the other drivers.

	[PATCH] USB: Important bugfix for UHCI list management code
	
	A major bug in the UHCI driver turned up recently.  Thanks to a lot of
	help from Simone Gotti it was identified and fixed late last week.  It
	turned out to be entirely my fault -- a previous patch had introduced two
	(!) errors.  (A combination of carelessness and a nasty thinko, and
	somehow it passed the regression tests...)
	
	Anyway, it's entirely possible that many of the problems people have been
	seeing are caused by that bug.  This patch is the solution.


	[PATCH] USB: fix cdc-acm as it is still (differently) broken


	[PATCH] USB: fix cdc-acm warnings due to previous patch

	It no longer has any callers.


	[PATCH] ppc64: iSeries virtual cdrom module fix
	
	From: Stephen Rothwell 
	
	This patch fixes loading viocd as a module.  It would oops because I was
	passing the address of a static buffer to dma_map_single and when loaded as
	a module, this address is not valid for that purpose.
	
	There are a couple of simple cleanups here as well.

	[PATCH] Set ARCH_MIN_TASKALIGN on ppc32
	
	From: Benjamin Herrenschmidt 
	
	From: David Woodhouse 
	
	Without this the task struct gets unaligned when using SLAB_DEBUG, causing
	random problems with FP and Altivec.


	[PATCH] sunrpc rmmod oops fix
	
	From: "J. Bruce Fields" 
	
	Unregister svcauth_gss caches on exit from gss module; fixes an oops on

	[PATCH] ppc64: add some iSeries proc entries
	
	From: Stephen Rothwell 
	
	This patch just adds some proc entries for the virtual tape and cdrom
	drivers to allow mapping between linux devices and OS/400 ones.  This is
	expected by existing users and there is no other way to do this
	translation.


	[PATCH] ppc64: Set ARCH_MIN_TASKALIGN
	
	From: Benjamin Herrenschmidt 
	
	We need some alignement of those structs for proper operations especially
	with FP and Altivec, or SLAB_DEBUG can break us.


	[PATCH] clean up Pentium M quirk code in nmi.c
	
	This simplifies the Pentium M quirk code in nmi.c, and eliminates an
	unnecessary apic_read().
	
	Local APIC accesses are not zero-cycle; let's not inflict more damage
	than we must.


	[PATCH] use smp_processor_id() in init_IRQ()
	
	This replaces current_thread_info()->cpu in i386' init_IRQ() by the
	equivalent smp_processor_id().
	
	Reduces overhead on UP, and makes the code cleaner.


	[PATCH] USB: ehci handles pci misbehavior better
	
	Cope better when PCI misbehaves badly and registers misbehave:
	
	    - terminate some loops before they get to infinity
	       * capability scan
	       * port reset
	    - after init failure, memory may already be cleaned up
	
	Some systems have been reporting such problems after ACPI resume.


	[PATCH] USB: rndis gadget driver updates
	
	Various build fixes:  64bit (Andrew Morton), static linking,
	broken on big-endian, etc.
	
	Tighten up the integration with the main "ether" driver, so
	state transitions and host ethernet addresses are shared too.
	Add missing spinlock calls around RNDIS command outcall,
	fix GET_INTERFACE issue, host mustn't clobber netdev flags.
	
	Minor code cleanups.


	[PATCH] USB: silence dpcm warning
	
	Warnings aren't terribly important in and of themselves, but there
	isn't really much the warning tells us to do here, so it would appear
	that caving in to the compiler is the thing to do for now.


	[PATCH] USB: tiglusb: wrong timeout value
	
	Hi,
	
	this patch (cumulative; 2.4 & 2.6) fixes another bug in the tiglusb
	driver. The formula used to calculate jiffies from timeout is wrong.
	The new formula is ok and takes care of integer computation/rounding.
	This is the same kind of bug than in the tipar char driver.


	[PATCH] USB: ftdi patch fixup
	
	I just checked out the latest 2.6.6-rc1-mm1 to see that the ID patch for
	ftdi has applied cleanly, but apparently someone was faster and in the
	combined ID table our ID's were missing.
	Most probably the patch program got confused and applied the hung at wrong
	spot..
	
	Attached is a patch that places that 2 lines in the correct spot.


	[PATCH] USB: usbnet and pl2301/2302 reset
	
	Handle some PL-2301/2302 devices better.


	RFC1002 fixup


	[PATCH] tipar char driver: wrong timeout value
	
	this patch (2.4 & 2.6) fixes a bug about the timeout value. The formula
	used to calculate jiffies from timeout is wrong.
	The new formula is ok and takes care of integer computation/rounding.
	There is the same bug in the tiglusb.c module which will be fixed by another
	patch.


	[PATCH] symlink doesn't support kobj name > 20 charaters (KOBJ_NAME_LEN)
	
	Since symlink.c uses "name" field of a kobj when it calculates the
	length,  it gets a wrong value if the kobj's name  has more than 20
	charathers.  A correct way to do that is to call kobject_name(kobj)
	instead of using kobj->name directly.


	exit from waiting on smb response when session dead


	Update change log for 1.10 cifs vfs


	ia64: Add message-queue support to copy_siginfo_from_user().


	proper rc on host down


	fix error code mapping on bad host


	fix timeout on close operation when pending signal


	NTFS: Move a few assignments after a NULL check in fs/ntfs/attrib.c.


	do not allow routine user signals to kill SendReceive wait for response (which was damaging performance badly)


	[PATCH] writeback livelock fix
	
	If a filesystem's ->writepage implementation repeatedly refuses to write the
	page (it keeps on redirtying it instead) (reiserfs seems to do this) then the
	writeback logic can get stuck repeately trying to write the same page.
	
	Fix that up by correctly setting wbc->pages_skipped, to tell the writeback
	logic that things aren't working out.


	NTFS: Finally fix NFS exporting of mounted NTFS volumes by checking the
	return of d_splice_alias() and acting accordingly rather than just
	ignoring the returned dentry.


	[SPARC64]: Update defconfig.


	[ARM PATCH] 1824/1: guard against gcc not respecting local variable register assignment
	
	Patch from Nicolas Pitre
	
	The recent discovery of a problem with gcc not always respecting register
	assignment for local variables to be used with inline assembly is worrisome.
	If unnoticed, such problems can cover bugs that might prove hard to find
	especially when the code is right but silently ignored.  This patch adds a
	test where needed to have the assembler confirm our register selection and
	fail the kernel build if the wrong registers are allocated.


	[ARM PATCH] 1825/1: abort on bad code generation with div64 in some cases
	
	Patch from Nicolas Pitre
	
	One case was found when the kernel is compiled with -O2 (instead of the 
	default -Os).  However, all gcc-3.* versions seem to have a problem with 
	this.  Instead of blacklisting them all unconditionally, better just abort
	when a bad case occurs especially since this bad case doesn't seem to
	appear with current default compiler flags.  Depends on patch #1824.


	[SPARC64]: Fix zero-extension issues wrt. {pgd,pmd}_val().


	[TCP]: Report vegas info via tcp_diag.


	[CRYPTO]: Add module autoloads for null module.


	[NET]: linux/if.h needs linux/compiler.h for __user.


	[ARM] Remove extraneous "volatile" from atomic_t pointers.


	[ARM PATCH] 1815/1: Generic DMA buffer bouncing support for ARM targets
	
	Patch from Deepak Saxena
	
	Latest (and hopefully last :) patch for generic DMA buffer bouncing.
	
	- Fixed SA1111 dma_needs_bounce
	- Added check for out of bounds buffers.
	- Made dmabounce.c directly implement dma_* API
	
	Note that I didn't do the following:
	
	#ifndef CONFIG_DMABOUNCE
	inline implementations of all functions
	#else
	extern declarations
	#endif
	
	Instead I wrapped it individual in #ifndef/#else blocks to keep the
	comments in the same area as function declarations.  IMHO this makes 
	it easier for someone to go look at the comments if they need to know 
	what a specific API does.
	


	[PATCH] e100: ICH 10/H Tx hang fix
	
	* Need to carry forward this workaround from old e100 driver to
	  avoid a Tx hang on ICH systems linked at 10/Half.  Workaround
	  adds a stall before each Tx command queued by issuing a NOP
	  command followed by 1us delay.  Yuck!  Otherwise HW locks hard.
	  (Probably needed for eepro100 also ;-).


	[netdrvr tulip] fix use-after-free
	
	The attached patch fixes an "oops" in tulip driver when a live interface
	is deactivated (i.e. PC Card ejected or module unloaded) without being
	brought down first.


	[PATCH] generic PCI IDE support for Toshiba Piccolo chips
	
	From: Daniel Drake 
	
	Adds Toshiba chips to the list supported by the generic PCI IDE driver.
	The 2.4 tree already contained an entry for 0x1179:0x0102, this patch
	adds that entry to 2.6 as well as two new ones (0x0103 and 0x0105).
	This then allows DMA to be enabled on disks.


	[PATCH] use kernel min/max in IDE code (1/2)
	
	From: Randy Dunlap 
	From: Michael Veeck 
	
	ide-cd.h: remove unnecessary MIN() macro
	ide-cd.c: change MIN() calls to use kernel.h calls
	ide-tape.c: use min_t()/max_t() instead of min()/max()


	[PATCH] use kernel min/max in IDE code (2/2)
	
	From: Randy Dunlap 
	From: Michael Veeck 
	
	Removes unnecessary IDE_MIN()/IDE_MAX() macros
	and changes calls to use kernel.h macros instead.


	[PATCH] prevent module unloading for legacy IDE chipset drivers
	
	It is unsafe thing to do (no locking, no reference counting etc).
	Just remove module_exit() as it was done for IDE PCI drivers.

	[PATCH] ISDN CAPI: add ncci list semaphore
	
	Fix race conditions of ISDN CAPI's internal ncci list handling by using
	a per capidev semaphore.


	[PATCH] don't log drive loading failures
	
	This is an old bug that often confuses people, rightfully.
	
	For some laptop and server type cdroms, the drives advertise themselves
	as tray loading even if they are caddy-like or slot-in loaders.  This
	means they cannot insert the media on their own, and this generates a
	5/24/00 error to START_STOP_UNIT.
	
	This prevents the logging of such a failure, and also fixes the
	generation of such a bad command in case the mech type was correctly set
	by the drive.


	[PATCH] USB: fix up fake usb_interface structure in hiddev
	
	This fixes a oops in the current kernel tree.


	[PATCH] USB: further cleanup of the hiddev driver, fixing another possible oops on disconnect.


	[PATCH] correct LoEj logic
	
	The logic got a little foo-bar'ed in the last patch, we should have keep
	the old logic.  Ie LoEj bit (2nd) must always be set, just clear it for
	known non-capable of loading drives.


	[PATCH] ia64: bug w/ shared interrupts
	
	I just ran into a bug introduced by the most recent iosapic.c patch.
	The scenario is a builtin driver is up and running happily.  A module
	loads for a devices that happens to share the same interrupt vector,
	in this case a network driver.  The module calls pci_enable_device()
	as it should, which eventually lands in iosapic_enable_intr().  We
	then proceed to mask the interrupt and kill the device that's already
	running.  As a bonus, request_interrupt() doesn't fix the problem
	because we only call the startup for the interrupt handler on the
	first action attached to the interrupt.
	
	I think the best way out of this is simply to detect when an action is
	already attached to a vector and leave it alone.  This also prevents
	interrupts from moving to other cpus (on boxes w/o irq redirection)
	for no good reason.


	[PATCH] ia64: Remove SN PDA page overflow check
	
	There's an obsolete check in sn_init_pdas() left over from the 2.4
	days that panics if the cpu PDA and cpu_data area span more than a page.
	With 2.6, we're not limited to a page, so remove the check entirely.


	[TCP]: Add vegas sysctl docs.


	[IPV4]: Spelling fixed for ip-sysctl.txt


	[IRDA]: Export irda_task_delete.


	[SUNRPC]: Missing NULL kmalloc check in unix_domain_find().


	[PATCH] One more USB fix
	
	Here's another fix it'd be good to merge ...
	
	No changes to the Linux code at all, but it'll makes the Windows
	configuration of a Linux device running the Ethernet/RNDIS gadget behave
	correctly on more versions of Windows.  (It might prevent some
	Bluescreening too.)


	[TG3]: Fix jimbo frame PHY programming.
	
	1. Added new workaround for 5705 to improve bit error rate.
	
	2. Changed to use read-modify-write to set the extended packet bit in
	tg3_phy_reset.
	
	3. Removed some phy setup code in tg3_phy_probe. All of that is already
	in the end of tg3_phy_reset. Writing to the phy during probe time may
	contend with ASF because ASF is constantly reading phy registers to
	determine the link.
	
	
	4. Removed the write to phy register 0x18 in tg3_phy_copper_begin. Not
	sure what it was for and it will overwrite that regsiter.


	[TG3]: Fix comment typo.


	[TG3]: Dump NIC-specific statistics via ethtool.
	
	Contributed by Tony Cureington @ HP, updated (from pre-ethtool_ops)
	and modified by me.


	[TG3]: Update driver version and reldate.


	[PATCH] create singlethread_workqueue()
	
	From: Rusty Russell 
	
	Workqueues are a great primitive for running things from user context from
	a completely clean environment.  Unfortunately, they currently insist on
	creating one thread per CPU, which is overkill for many situations, so the
	more generic keventd workqueue is used for these.  Recently deadlocks using
	keventd were demonstrated, showing that it is not suitable for all uses.
	
	1) Clean up CPU iterators.  Always a nice touch.
	
	2) Add __create_workqueue() and create_singlethread_workqueue(),
	   keeping source compatibility.
	
	3) Put workqueues in workqueue list even if !CONFIG_HOTPLUG_CPU (means
	   we need a lock to protect that list).  Now we can tell if a wq is
	   single-threaded using list_empty(&wq->list).
	
	4) For single-threaded workqueues, override CPU in queue_work,
	   delayed_work_timer_fn and flush_workqueue to be 0.  flush_workqueue
	   now does redundant passes for single-threaded workqueues, but the
	   code remains simple.
	
	5) Make create_workqueue_thread return the thread, so we can easily
	   kthread_bind for multi-threaded workqueues.
	
	
	akpm fixes:
	
	- Fix up is_single_threaded() handling
	
	- single-threaded wq thread does not have "/0" appended.


	[PATCH] Use workqueue for call_usermodehelper
	
	From: Rusty Russell 
	
	call_usermodehelper uses keventd to create a thread, guaranteeing a nice,
	clean kernel thread.  Unfortunately, there is a case where
	call_usermodehelper is called with &bus->subsys.rwsem held (via
	bus_add_driver()), but keventd could be running bus_add_device(), which is
	blocked on the same lock.  The result is deadlock, and it comes from using
	keventd for both.
	
	In this case, it can be fixed by using a completely independent thread for
	call_usermodehelper, or an independent workqueue.  Workqueues have the
	infrastructure we need, so we use one.
	
	Move EXPORT_SYMBOL while we're there, too.
	
	akpm fixes: Make it compile with !CONFIG_KMOD


	[PATCH] reiserfs: ignore prepared and locked buffers
	
	From: Chris Mason 
	
	block_write_full_page might see and lock clean metadata buffers, which leads
	to bogus vs-12339 messages.  Change the message to ignore bh locked.


	[PATCH] credentials locking fix
	
	From: Chris Wright 
	
	Contributions from:
	Stephen Smalley 
	Andy Lutomirski 
	
	During exec the LSM bprm_apply_creds() hooks may tranisition the program to a
	new security context (like setuid binaries).  The security context of the new
	task is dependent on state such as if the task is being ptraced.  
	
	ptrace_detach() doesn't take the task_lock() when clearing task->ptrace.  So
	there is a race possible where a process starts off being ptraced, the
	malicious ptracer detaches and if any checks agains task->ptrace are done more
	than once, the results are indeterminate.
	
	This patch ensures task_lock() is held while bprm_apply_creds() hooks are
	called, keeping it safe against ptrace_attach() races.  Additionally, tests
	against task->ptrace (and ->fs->count, ->files->count and ->sighand->count all
	of which signify potential unsafe resource sharing during a security context
	transition) are done only once the results are passed down to hooks, making it
	safe against ptrace_detach() races.
	
	Additionally:
	
	- s/must_must_not_trace_exec/unsafe_exec/
	- move unsafe_exec() call above security_bprm_apply_creds() call rather than
	  in call for readability.
	- fix dummy hook to honor the case where root is ptracing
	- couple minor formatting/spelling fixes


	[PATCH] ext3 journalled quota locking fix
	
	From: Jan Kara 
	
	I've attached a fix for a problem in ext3 journalled quota patch - the problem
	is that detecting whether dqput() sleeps was wrong and so we could possibly
	schedule when holding a spinlock.


	[PATCH] Bigger quota hashtable
	
	From: Jan Kara 
	
	I found out that quota uses hash table with just 43 entries to hash dquot
	entries.  I guess that we can afford using one page for that
	(quotactl(Q_GETQUOTA...), got faster like 3x for 4000 users).  Attached patch
	implements that.


	[PATCH] Per-sb dquot dirty lists
	
	From: Jan Kara 
	
	When there are lots of dirty dquots the vfs_quota_sync() is too slow (it has
	O(N^2) behaviour).  Attached patch implements list of dirty dquots for each
	superblock and quota type.  Using this lists sync is trivially linear.
	Attached patch is against 2.6.5 with journalled quota and previous patch for
	hash table size.
	
	(Jan had a test which went from 8 minutes to 0.8 seconds...)


	[PATCH] dquot: remove unneeded test
	
	We're testing the nullness of `sb' potentially after rereferencing it
	(although the compiler will have reordered things to avoid such a bug).
	
	Just remove the test - the superblock pointer shouldn't be null in there.


	[PATCH] Minor fixes for ext3 journalled quotas
	
	From: Jan Kara 
	
	It fixes a memory leak when turning journalled quotas off.


	[PATCH] ppc64: Split prom.c Into pre-reloc and post-reloc Functions
	
	From: Rusty Russell 
	
	Move all the functions that run normally (ie.  with the kernel in the correct
	address) to the bottom of prom.c, and keep all the functions which use RELOC()
	to the top, above "prom_init()" which calls them.
	
	Also, make prom_initialize_dart_table and prom_initialize_tce_table static.


	[PATCH] ppc64: Rearrage finish_device_tree() and its functions in C Order
	
	From: Rusty Russell 
	
	Rather than pre-declaring static functions, order them so it's not neccessary.
	This makes the code easier to navigate and patch.


	[PATCH] ppc64: Rearrage copy_device_tree() and its functions in C Order
	
	From: Rusty Russell 
	
	Rather than pre-declaring static functions, order them so it's not neccessary.
	This makes the code easier to navigate and patch.


	[PATCH] ppc64: Rearrage interpret_funcs in C Order
	
	From: Rusty Russell 
	
	Rather than pre-declaring static functions, order them so it's not neccessary.
	This makes the code easier to navigate and patch.


	[PATCH] ppc64: Rearrage Rest of prom.c in C Order
	
	From: Rusty Russell 
	
	Rather than pre-declaring static functions, order them so it's not neccessary.
	This makes the code easier to navigate and patch.


	[PATCH] ppc64: Make finish_device_tree use lmb_alloc, not klimit
	
	From: Rusty Russell 
	
	finish_device_tree simply allocates nodes by incrementing klimit (ie.  using
	memory on top of the kernel).  Change it to figure out how much memory it
	needs, then use lmb_alloc to allocate that, then fill it in.
	
	This gets rid of the only manipulation of klimit after prom_init.


	[PATCH] ppc64: make_room macro for ppc64 prom.c
	
	From: Rusty Russell 
	
	copy_device_tree calls inspect_node() which recurses to copy the Open Firmware
	device tree.  It just copied into memory above the kernel for about 8MB, which
	can overwrite the initrd, and/or get truncated on big machines.
	
	The real solution is to allocate memory properly for all the prom_init memory
	users.  However, that's quite a change.  This patch introduces a "make_room"
	macro which inspect_node uses to get memory.  This does the same as before,
	except skips over the initrd if neccessary.


	[PATCH] ppc64: Fix prom.c to boot on G5 after make_room fix
	
	From: Rusty Russell 
	
	Ben Herrenschmidt made this actually boot.


	[PATCH] ppc64: Clean up prom functions in prom.c
	
	From: Rusty Russell 
	
	1) Define PROM_ERROR: checks for call_prom() < 0 are bogus (returns ulong)
	2) All OF access functions should be marked __init.
	3) prom_strtoul isn't used at all.


	[PATCH] ppc64: Initrd Cleanup
	
	From: Rusty Russell 
	
	Clean up initrd handling.
	
	1) Expose initrd_start and initrd_end to prom.c (replacing its local
	   initrd_start and initrd_len).
	
	2) Don't hand mem (aka klimit) through functions which don't need it.
	
	3) Add more debugging under DEBUG_PROM in case we broke anything.


	[PATCH] ppc64: Move Initrd
	
	From: Rusty Russell 
	
	This patch moves the initrd when "make_room" runs out of space, rather than
	stepping over it.  The problem with stepping over it is that it gets copied
	with the kernel when this happens, which wastes space.
	
	Also ensures that the initrd isn't where the kernel wants to be moved to: if
	it is, it gets moved out the way.


	[PATCH] ppc64: prom.c fix for CONFIG_BLK_DEV_INITRD=n
	
	From: Rusty Russell 
	
	Doesn't compile with CONFIG_BLK_DEV_INITRD=n.  Be more careful with the
	conditionals.
	
	Spotted by Dave Boutcher...


	[PATCH] hugetlbpage: remove include linux/module.h
	
	From: Paul Jackson 
	
	The #include of linux/module.h in several arch/*/mm/hugetlbpage.c files for
	EXPORT_SYMBOL(hugetlb_total_pages) is now unneeded.


	[PATCH] slab alignment fixes
	
	From: Manfred Spraul 
	
	Below is a patch that redefines the kmem_cache_alloc `align' argument:
	
	- align not zero: use the specified alignment.  I think values smaller than
	  sizeof(void*) will work, even on archs with strict alignment requirement (or
	  at least: slab shouldn't crash.  Obviously the user must handle the
	  alignment properly).
	
	- align zero:
	* debug on: align to sizeof(void*)
	* debug off, SLAB_HWCACHE_ALIGN clear: align to sizeof(void*)
	* debug off, SLAB_HWCACHE_ALIGN set: align to the smaller of
	   - cache_line_size()
	   - the object size, rounded up to the next power of two.
	  Slab never honored cache align for tiny objects: otherwise the 32-byte
	  kmalloc objects would use 128 byte objects.
	
	There is one additional point: right now slab uses ints for the bufctls.
	Using short would save two bytes for each object.  Initially I had used short,
	but davem objected.  IIRC because some archs do not handle short efficiently. 
	Should I allow arch overrides for the bufctls?  On i386, saving two bytes
	might allow a few additional anon_vma objects in each page.


	[PATCH] prune_dcache comment fix
	
	From: Maneesh Soni 
	
	Clarify some things which were confusing poeple...


	[PATCH] m68k: Amiga A2065 Ethernet KERN_*
	
	From: Geert Uytterhoeven 
	
	Amiga A2065 Ethernet: Add KERN_* prefixes to printk() messages


	[PATCH] m68k bitops
	
	From: Geert Uytterhoeven 
	
	M68k bitops updates (from Roman Zippel):
	  - Optimize find_{first,next}_zero_bit()
	  - Add missing implementations of find_{first,next}_bit()


	[PATCH] efivars: remove from arch/ia64
	
	From: Matt Tolentino 
	
	I broke up the efivars driver update patch I had sent out quite a while ago
	into several smaller patches.  This includes several fixes and suggestions
	that were pointed out.  The patches are broken down as follows:
	
	1 - remove all traces of efivars from arch/ia64/
	2 - add new sysfs based efivars driver into
	    drivers/firmware with accompanying Kconfig/Makefile
	    changes to make it fully functional for ia64 again.
	3 - cleans up x86 references to the /proc version of
	    the efivars driver.


	[PATCH] efivars: add to drivers/firmware
	
	From: Matt Tolentino 
	
	Second efivars driver update patch that adds efivars into the drivers/firmware
	directory.


	[PATCH] efivars: remove x86 references
	
	From: Matt Tolentino 
	
	Third efivars driver update patch that removes x86 references to the /proc
	version of the driver.


	[PATCH] efivars fixes
	
	From: Matt Domsch 
	
	Patch below fixes three small bugs in efivars.c as posted by Matt Tolentino
	last week and included in the latest -mm.  Aside from this small patch, I'm
	quite pleased with Matt T's work, thanks!
	
	- dummy() used for reading write-only sysfs files should return -ENODEV to
	  indicate failure, not 0.
	
	- efivar_create() should return the number of bytes written on success, not
	  zero.
	
	- efivar_delete() should return the number of bytes written on success, not
	  zero.


	[PATCH] efibootmgr location change
	
	From: Matt Domsch 
	
	I moved the home of the efibootmgr utility from domsch.com to
	linux.dell.com.  Note the move in drivers/firmware/Kconfig, also note
	version 0.5.0-test3 or above is necessary.


	[PATCH] s390: no timer interrupts in idle.
	
	From: Martin Schwidefsky 
	
	This patch add a system control that allows to switch off the jiffies timer
	interrupts while a cpu sleeps in idle.  This is useful for a system running
	with virtual cpus under z/VM.


	[PATCH] task_lock() comment update


	[PATCH] dio_bio_reap() return value fix
	
	This function doesn't correctly accumulate -EIO for its caller.


	[PATCH] fix CONFIG_SYSFS=n compile warning
	
	From: Matt Mackall 


	[PATCH] isofs "default NLS charset not used" fix
	
	From: Marek Szuba 
	
	Use the configured default NLS rather than hardwire it.


	[PATCH] slab: use order 0 for vfs caches
	
	We have interesting deadlocks when slab decides to use order-1 allocations for
	ext3_inode_cache.  This is because ext3_alloc_inode() needs to perform a
	GFP_NOFS 1-order allocation.
	
	Sometimes the 1-order allocation needs to free a huge number of pages (tens of
	megabytes) before a 1-order grouping becomes available.  But the GFP_NOFS
	allocator cannot free dcache (and hence icache) due to the deadlock problems
	identified in shrink_dcache_memory().
	
	So change slab so that it will force 0-order allocations for shrinkable VFS
	objects.  We can handle those OK.


	[PATCH] smb_writepage retval fix
	
	->writepage() is supposed to return zero or a negative error code.  Returning
	the number of bytes written will confuse the VFS.


	[PATCH] simplify put_page()
	
	By requiring that compound pages implement destructors we can drop some code
	from put_page().


	[PATCH] hugepage fixes
	
	From: William Lee Irwin III 
	
	mm/hugetlb.c is putting the destructor in head->lru.prev not head[1].mapping;
	fix below along with nuking huge_page_release(), which simply duplicates
	put_page().


	[PATCH] ISDN Eicon driver: remove call to trap usermode helper
	
	From: Armin Schindler 
	
	This patch removes the function to call a usermode helper if the hardware
	and its firmware has a problem.  This feature is already implemented in the
	user utility and the driver does not need to care about it.


	[PATCH] doc: tips for S3 resume on radeon cards
	
	From: Pavel Machek 
	
	Stefan has pretty useful tips for getting S3 to work on radeon notebooks.
	This brings whole new class of systems to be usable for S3.


	[PATCH] ppc32: fix head_44x.S copyrights
	
	From: Matt Porter 
	
	A copyright change to properly show the lineage of this file.


	[PATCH] fs/proc/array.c: workaround for gcc-2.96
	
	From: Alan Stern 
	
	This patch is needed to work around gcc-2.96's limited ability to cope with
	long long intermediate expression types.  I don't know why the code
	compiled okay earlier and failed now.


	[PATCH] blkdev.h: functions no longer inline
	
	From: "Randy.Dunlap" 
	
	These are EXPORTed SYMBOLs; 'inline' was removed from them in ll_rw_blk.c
	on 2002-11-25.


	[PATCH] nfs_writepage() retval fix
	
	Both ->writepage() and ->writepages() should return 0 or a negative error
	code.  It shouldn't return the number of bytes which were written.
	
	From: Trond Myklebust 
	
	   Redirty the page if all of the modified parts of the page weren't
	   written out.


	[PATCH] ppc32: dma_unmap_page() fix
	
	From:  (Arthur Othieno)
	
	Duplicate definition of dma_unmap_single() should actually be
	dma_unmap_page().

	[PATCH] fix fs/proc/task_nommu.c compile
	
	From: Christoph Hellwig 
	
	this file has been broken for ages, but it seems few !CONFIG_MMU users use
	mainline at all.


	[PATCH] remove Documentation/DocBook/parportbook.tmpl
	
	From: Christoph Hellwig 
	
	The partportbook is licensed under the GFDL and Linus agreed to remove
	all GFDL licensed files in
	http://www.ussg.iu.edu/hypermail/linux/kernel/0306.1/1968.html.
	
	I pinged the author the first time on the 2nd of april but still didn't get
	a reply, then send a patch to Linus to remove it last week but linus
	ignored it.  Here's the patch again:


	[PATCH] Set module license in mcheck/non-fatal.c
	
	From: Herbert Xu 
	
	This patch sets the module license for mcheck/non-fatal.c.  The module
	doesn't work at all without this as one of the symbols it needs is only
	exported as GPL.


	[PATCH] SubmittingPatches diffing update.
	
	From: Zwane Mwaikambo 
	
	A kernel janitor recently got confused by the advice in SubmittingPatches
	and was sending patches with the wrong strip level, i think just about
	everyone would prefer standard patches.  Also mention various patch
	management scripts for batching up large deltas.


	[PATCH] ppc64: remove duplicated mb() and comment from __cpu_up
	
	From: Nathan Lynch 
	
	This seems to have slipped in during a manual merge at some point.


	[PATCH] SELinux ptrace race fix
	
	From: Stephen Smalley 
	
	Looking again at the SELinux ptrace check, I believe that there is an
	unrelated race due to the fact that the parent link is only updated after
	releasing the task lock in ptrace_attach (and this is necessary as task lock
	doesn't nest with write lock of tasklist_lock).
	
	The patch below changes SELinux to save the tracing process' SID upon a
	successful selinux_ptrace hook call and then use that SID in the ptrace check
	in apply_creds in order to avoid such races.  This allows us to preserve the
	fine-grained process-to-process ptrace check upon exec (vs.  the global
	CAP_SYS_PTRACE privilege => PT_PTRACE_CAP flag used by the capability module)
	while still avoiding races.


	[PATCH] doc: specifiying module parameters
	
	From: "Randy.Dunlap" 
	
	kernel-parameters.txt: add info on how to specify loadable module
	parameters vs.  built-in module parameters


	[PATCH] kbuild: Improved external module support
	
	From: Sam Ravnborg 
	
	The external module support recently introduced caused a number of problems:
	- To build an external module the Module.symvers file was needed
	- To create the Module.symvers file a module was required
	- If Module.symvers was missing kbuild boiled out with an error
	- If vmlinux was missing also the stage 2 of module build failed (make -k)
	- It was not documented what was needed to actually bauild a module
	
	The following patch addresses this by adding the following functionality:
	- Always generate the Module.symvers file
	- Ignore a missing Module.symvers file
	- Add a new target modules_prepare, it prepares the kernel for building
	  external modules, and is also usefull with O=
	- And it adds some more comments to Makefile.modpost, so others may follow
	  it with some luck
	- .modpost.cmd is no longer generated
	
	This should close all reports on issues with respect to building external
	modules with current kernel - which has been identified as kernel problems.


	JFS: Fix non-ascii file name problem
	
	An unintentional sign extention caused non-ascii characters to be
	stored incorrectly, leading to inaccessible files.  Changing a
	declaration to unsigned char fixes the problem.


	[PATCH] fix SG_IO page leak
	
	We cannot always rely on ->biotail remaining untouched. Currently we
	leak all the pinned user pages when doing cdda ripping at least, so I
	see no way around keeping the bio pointer seperate and passing it back
	in for unmap. Alternatively, we could invent a struct blk_map_data and
	put it on the stack for passing to both map and unmap.


	Include  in files that need them.


	[CRYPTO]: Add module aliases for des and sha512.


	[TG3]: Undo comment typo fix, it was wrong.


	[COMPAT]: HDIO_DRIVE_TASK is a compatible ioctl.


	[PATCH] Fix cpumask iterator over empty cpu set
	
	Can't use _ffs() without first checking for zero, and if bits beyond
	NR_CPUS set it'll give bogus results.  Use find_first_bit
