f26fdd5992 [PATCH] CHECK_IRQ_PER_CPU() to avoid dead code in __do_IRQ()
IRQ_PER_CPU is not used by all architectures.  This patch introduces the
macros ARCH_HAS_IRQ_PER_CPU and CHECK_IRQ_PER_CPU() to avoid the generation
of dead code in __do_IRQ().

ARCH_HAS_IRQ_PER_CPU is defined by architectures using IRQ_PER_CPU in their
include/asm_ARCH/irq.h file.

Through grepping the tree I found the following architectures currently use
IRQ_PER_CPU:

        cris, ia64, ppc, ppc64 and parisc.

5e1efe4931 [PATCH] jffs/jffs2: remove wrong function prototypes
This patch removes prototypes for the generic_file_open and
generic_file_llseek functions.

Besides being superfluous because they are already present in fs.h, they
were also wrong because the actual functions aren't weak functions.

ffdfc40976 [PATCH] Add rdinit parameter to pick early userspace init
Since early userspace was added, there's no way to override which init to
run from it.  Some people tack on an extra cpio archive with a link from
/init depending on what they want to run, but that's sometimes impractical.

Changing the "init=" to also override the early userspace isn't feasible,
since it is still used to indicate what init to run from disk when early
userspace has completed doing whatever it's doing (i.e.  load filesystem
modules and drivers).

Instead, introduce "rdinit=" and make it override the default "/init" if
specified.

2b579beec2 [PATCH] proc: link count fix
This patch fixes bug titled "sunrpc as module and bad proc/sys link count"
reported by Jiri Slaby.

The problem was, that only proc_dir_entry->nlink was updated and the
corresponding inode->i_nlink was not.  The fix is to implement the
inode->getattr() method, and update i_nlink (if necessary).

A quick audit of proc code shows that no other attribute changes after
creation.

f3ef6f63e5 [PATCH] Speedup FAT filesystem directory reads
OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>

This speeds up directory reads for large FAT partitions, if the buffercache
has to be filled from the drive. Following values were taken from:

        $ time find path_to_freshly_mounted_fat > /dev/null

on an otherwise idle system.

FAT with 16KB Clusters on IDE attached drive:   Factor  2
FAT with 32KB Clusters on USB2 attached drive:  Factor 10 (!)
Its less than 1/10 slower, if the buffercache is uptodate.

The patch introduces the new function fat_dir_readahead().

fat_dir_readahead() calls sb_breadahead() to readahead a whole cluster,
if the requested sector is the first one in a cluster.
It is usefull to do this, because on FAT directories occupy whole
clusters, with the exception of FAT12/FAT16 root dirs.

Readahead is only done, if the cluster's first sector is not uptodate
to avoid overhead, when the buffer cache is already uptodate.
Note that under memory pressure, the maximal byte count wasted
(read: has to be red from disk twice) is 1 cluster's size.  Thats 64KB.

fat_dir_readahead() is called from fat__get_entry().

There is also an unrelated cleanup at one spot:

        if (bh)
                brelse(bh);

is replaced with:

        brelse(bh);

brelse() can handle NULL pointer arguments by itself.

f35279d3f7 [PATCH] sunrpc: cache_register can use wrong module reference
When registering an RPC cache, cache_register() always sets the owner as the
sunrpc module.  However, there are RPC caches owned by other modules.  With
the incorrect owner setting, the real owning module can be removed potentially
with an open reference to the cache from userspace.

For example, if one were to stop the nfs server and unmount the nfsd
filesystem, the nfsd module could be removed eventhough rpc.idmapd had
references to the idtoname and nametoid caches (i.e.
/proc/net/rpc/nfs4.<cachename>/channel is still open).  This resulted in a
system panic on one of our machines when attempting to restart the nfs
services after reloading the nfsd module.

The following patch adds a 'struct module *owner' field in struct
cache_detail.  The owner is further assigned to the struct proc_dir_entry
in cache_register() so that the module cannot be unloaded while user-space
daemons have an open reference on the associated file under /proc.

486d46aefe [PATCH] optimize writer path in time_interpolator_get_counter()
Christoph Lameter <clameter@engr.sgi.com>

When using a time interpolator that is susceptible to jitter there's
potentially contention over a cmpxchg used to prevent time from going
backwards.  This is unnecessary when the caller holds the xtime write
seqlock as all readers will be blocked from returning until the write is
complete.  We can therefore allow writers to insert a new value and exit
rather than fight with CPUs who only hold a reader lock.

8fc2751beb [PATCH] disk quotas fail when /etc/mtab is symlinked to /proc/mounts
If /etc/mtab is a regular file all of the mount options (of a file system)
are written to /etc/mtab by the mount command.  The quota tools look there
for the quota strings for their operation.  If, however, /etc/mtab is a
symlink to /proc/mounts (a "good thing" in some environments) the tools
don't write anything - they assume the kernel will take care of things.

While the quota options are sent down to the kernel via the mount system
call and the file system codes handle them properly unfortunately there is
no code to echo the quota strings into /proc/mounts and the quota tools
fail in the symlink case.

The attached patchs modify the EXT[2|3] and JFS codes to add the necessary
hooks.  The show_options function of each file system in these patches
currently deal with only those things that seemed related to quotas;
especially in the EXT3 case more can be done (later?).

Jan Kara also noted the difficulty in moving these changes above the FS
codes responding similarly to myself to Andrew's comment about possible
VFS migration. Issue summary:

 - FS codes have to process the entire string of options anyway.

 - Only FS codes that use quotas must have a show_options function (for
   quotas to work properly) however quotas are only used in a small number
   of FS.

 - Since most of the quota using FS support other options these FS codes
   should have the a show_options function to show those options - and the
   quota echoing becomes virtually negligible.

Based on feedback I have modified my patches from the original:

   JFS a missing patch has been restored to the posting
   EXT[2|3] and JFS always use the show_options function
       - Each FS has at least one FS specific option displayed
       - QUOTA output is under a CONFIG_QUOTA ifdef
       - a follow-on patch will add a multitude of options for each FS
   EXT[2|3] and JFS "quota" is treated as "usrquota"
   EXT3 journalled data check for journalled quota removed
   EXT[2|3] mount when quota specified but not compiled in

 - no changes from my original patch.  I tested the patch and the codes
   warn but

 - still mount.  With all due respection I believe the comments
   otherwise were a

 - misread of the patch.  Please reread/test and comment.  XFS patch
   removed - the XFS team already made the necessary changes EXT3 mixing
   old and new quotas are handled differently (not purely exclusive)

 - if old and new quotas for the same type are used together the old
   type is silently depricated for compatability (e.g.  usrquota and
   usrjquota)

 - mixing of old and new quotas is an error (e.g.  usrjquota and
   grpquota)

ea2f1590aa [PATCH] yenta: make ToPIC95 bridges work with 16bit cards
ToPIC95 brides (and maybe some other too) require to use the ExCA registers
to power up the socket if a 16bit card is pluged.  allow socket drivers to
set a flag so that yenta does just that.  also clean up yenta_get_status()
a bit to use the new yenta_get_power() function.

Side note: ToPIC97 bridges (at least in Rev.5 i have) don't require this.

Ryan Underwood <nemesis-lists@icequake.net> said:

 According to the mail that David Hinds received from a Toshiba engineer,
 ToPIC95 and 97 do require this, and ToPIC100 does not.  Maybe you have a
 later revision.

 For all chips, 16-bit cards can be enabled through ExCA.  So doesn't it
 make sense just to make this the default behavior for all Toshiba chips,
 to avoid corner cases showing up later?

Daniel responded:

 I disagree with ryan to change anything for topic97 bridges.  they work.
 and I couldn't find (read google) any report of a topic97 breaking on
 applying power with the CB registers.

 I'm having several toshba notebooks at work (and home) with topic95,97,100
 bridges.  Only the ones with a topic95 didn't work.

32605a1815 [PATCH] radix_tag_get(): differentiate between no present node and tag unset cases
Simple patch to radix_tree_tag_get() to return different values for non
present node and tag unset.

The function is not used by any in-kernel callers (yet), but this
information is definitely useful.

201b6264ff [PATCH] radix-tree: Remove unnecessary indirections and clean up code
- There is frequent use of indirections in the radix code. This patch
  removes those indirections, makes the code more readable and allows
  the compilers to generate better code.

- Removing indirections allows the removal of several casts.

- Removing indirections allows the reduction of the radix_tree_path
  size from 3 to 2 words.

- Use pathp-> consistently.

- Remove unnecessary tmp variable in radix_tree_insert

- Separate the upper layer processing from the lowest layer in __lookup()
  in order to make it easier to understand what is going on and allow
  compilers to generate better code for the loop.

987132bb0b [PATCH] Support powering sharp zaurus sl-5500 LCD up and down
This adds support for powering Zaurus's video up and down.  PDA without
screen is kind of useless, so it is quite important...  I'll have to figure
out how to really control the frontlight, because LCD without that is quite
hard to read.

202e5979af [PATCH] compat: be more consistent about [ug]id_t
When I first wrote the compat layer patches, I was somewhat cavalier about
the definition of compat_uid_t and compat_gid_t (or maybe I just
misunderstood :-)).  This patch makes the compat types much more consistent
with the types we are being compatible with and hopefully will fix a few
bugs along the way.

	compat type		type in compat arch
	__compat_[ug]id_t	__kernel_[ug]id_t
	__compat_[ug]id32_t	__kernel_[ug]id32_t
	compat_[ug]id_t		[ug]id_t

The difference is that compat_uid_t is always 32 bits (for the archs we
care about) but __compat_uid_t may be 16 bits on some.

19306059cd [PATCH] NMI: Update NMI users of RCU to use new API
Uses of RCU for dynamically changeable NMI handlers need to use the new
rcu_dereference() and rcu_assign_pointer() facilities.  This change makes
it clear that these uses are safe from a memory-barrier viewpoint, but the
main purpose is to document exactly what operations are being protected by
RCU.  This has been tested on x86 and x86-64, which are the only
architectures affected by this change.

fe21773d65 [PATCH] Provide better printk() support for SMP machines
The attached patch prevents oopses interleaving with characters from
other printks on other CPUs by only breaking the lock if the oops is
happening on the machine holding the lock.

It might be better if the oops generator got the lock and then called an
inner vprintk routine that assumed the caller holds the lock, thus
making oops reports "atomic".

b3dbb4ecd4 [PATCH] kallsyms: change compression algorithm
This patch changes the way the compression algorithm works.  The base
algorithm is similiar to the previous but we force the compressed token
size to 2.

Having a fixed size compressed token allows for a lot of optimizations, and
that in turn allows this code to run over *all* the symbols faster than it
did before over just a subset.

Having it work over all the symbols will make it behave better when symbols
change positions between passes, and the "inconsistent kallsyms" messages
should become less frequent.

In my tests the compression ratio was degraded by about 0.5%, but the
results will depend greatly on the number of symbols to compress.
