[PATCH] ppc32: Small build fix for alsa powermac

My newer iMac mini driver doesn't build with verbose debug enabled.

This fixes it, and removes an erroneous error printk (since it's normal
on some machine to not find some gpios on the "first try").

[PATCH] ppc32: Workaround a cache flush issue on sleep

We are experiencing a problem when flushing the CPU caches before sleep
on some laptop models using the 750FX CPU rev 1.X. While I haven't been
able to figure out a proper explanation for what's going on, I do have a
workaround that seem to work reliably and allows those machine to sleep
and wakeup properly again.

I'll re-update that code if/when I ever find exactly what is happening
with those CPU revisions.

[PATCH] DocBook: changes and extensions to the kernel documentation

I have recompiled Linux kernel 2.6.11.5 documentation for me and our
university students again.  The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels.  I
have tried to proceed with that task.  I have done that more times from 2.6.0
time and it gets boring to do same changes again and again.  Linux kernel
compiles after changes for i386 and ARM targets.  I have added references to
some more files into kernel-api book, I have added some section names as well.
 So please, check that changes do not break something and that categories are
not too much skewed.

I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention.  Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors.  Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.

You can see result of the modified documentation build at
  http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz

Some more sources are ready to be included into kernel-doc generated
documentation.  Sources has been added into kernel-api for now.  Some more
section names added and probably some more chaos introduced as result of quick
cleanup work.

[PATCH] ext3: remove unnecessary race then retry in ext3_get_block

The extra race-with-truncate-then-retry logic around
ext3_get_block_handle(), which was inherited from ext2, becomes unecessary
for ext3, since we have already obtained the ei->truncate_sem in
ext3_get_block_handle() before calling ext3_alloc_branch().  The
ei->truncate_sem is already there to block concurrent truncate and block
allocation on the same inode.  So the inode's indirect addressing tree
won't be changed after we grab that semaphore.

We could, after get the semaphore, re-verify the branch is up-to-date or
not.  If it has been changed, then get the updated branch.  If we still
need block allocation, we will have a safe version of the branch to work
with in the ext3_find_goal()/ext3_splice_branch().

The code becomes more readable after remove those retry logic.  The patch
also clean up some gotos in ext3_get_block_handle() to make it more
readable.

[PATCH] reiserfs endianness: sanitize reiserfs_key union

Since we only access reiserfs_key ->u.k_offset_v2 guts in four helper
functions, we are free to sanitize those, as long as

- layout of the structure is unchanged (it's on-disk object)

- behaviour of these helpers is same as before.

Patch kills the mess with endianness-dependent bitfields and replaces them
with a single __le64.  Helpers are switched to straightforward shift/and/or.

Benefits:

- exact same definitions for little- and big-endian architectures; no ifdefs
  in sight.

- generate the same code on little-endian and improved on big-endian.

- doesn't rely on lousy bitfields handling in gcc codegenerator.

- happens to be standard C (unsigned long long is not a valid type for a
  bitfield; it's a gccism and not well-implemented one, at that).

Al Viro [Sun, 1 May 2005 15:59:19 +0000]
[PATCH] reiserfs endianness: comp_short_keys() cleanup

comp_short_keys() massaged into sane form, which kills the last place where
pointer to in_core_key (or any object containing such) would be cast to or
from something else.  At that point we are free to change layout of
in_core_key - nothing depends on it anymore.

So we drop the mess with union in there and simply use (unconditional) __u64
k_offset and __u8 k_type instead; places using in_core_key switched to those.
That gives _far_ better code than current mess - on all platforms.

[PATCH] new valid_signal() function

This patch adds a new function valid_signal() that tests if its argument is
a valid signal number.

The reasons for adding this new function are:

- some code currently testing _NSIG directly has off-by-one errors.
  Using this function instead avoids such errors.

- some code currently tests unsigned signal numbers for <0 which is
  pointless and generates warnings when building with gcc -W.  Using this
  function instead avoids such warnings.

I considered various places to add this function but eventually settled on
include/linux/signal.h as the most logical place for it.  If there's some
reason this is a bad choice then please let me know (hints as to a better
location are then welcome of course).

idea as the BMC may be performing other important functions and a reset

[PATCH] vgacon: set vc_hi_font_mask correctly

When allocating a new VC with vgacon_init(), the font is shared across all
the VGA consoles.  However, the font mask was always set to the default
value of zero in visual_init(), even if we were using 512 character fonts
at the time.

Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the
console driver thinks it's already in 512 character mode.  This means that
to *fix* it, you'd actually have to take the console out of 512 character
mode and then set it back.

The attached sets vc_hi_font_mask in vgacon_init() for any new consoles
opened if the vgacon driver is already in 512 character mode, solving this.

This bug goes back to 2.4.18 at least, probably earlier.

This patches adds the "nbds_max" parameter to the nbd kernel module, which
limits the number of nbds allocated.  Previously, always all 128 entries
were allocated unconditionally, which used to waste resources and

[PATCH] reiserfs: make resize option auto-get new device size

It's trivial for the resize option to auto-get the underlying device size,
while it's harder for the user.  I've copied the code from jfs.

Since of the different reiserfs option parser (which does not use the
superior match_token used by almost every other filesystem), I've had to
use the "resize=auto" and not "resize" option to specify this behaviour.
Changing the option parser to the kernel one wouldn't be bad but I've no
time to do this cleanup in this moment.

Btw, the mount(8) man page should be updated to include this option.  Cc
the relevant people, please (I hope I cc'ed the right people).

[PATCH] Deprecate synchronize_kernel, GPL replacement

The synchronize_kernel() primitive is used for quite a few different purposes:
waiting for RCU readers, waiting for NMIs, waiting for interrupts, and so on.
This makes RCU code harder to read, since synchronize_kernel() might or might
not have matching rcu_read_lock()s.  This patch creates a new
synchronize_rcu() that is to be used for RCU readers and a new
synchronize_sched() that is used for the rest.  These two new primitives
currently have the same implementation, but this is might well change with
additional real-time support.  Both new primitives are GPL-only, the old
primitive is deprecated.

I will also be following this message with RFC patches that introduce two

becomes deprecated.

[PATCH] procfs: Fix hardlink counts for /proc/<PID>/task

The current logic assumes that a /proc/<PID>/task directory should have a
hardlink count of 3, probably counting ".", "..", and a directory for a
single child task.

It's fairly obvious that this doesn't work out correctly when a PID has
more than one child task, which is quite often the case.

The pid directories in /proc/ currently return the wrong hardlink count - 3,
when there are actually 4 : ".", "..", "fd", and "task".

This is easy to notice using find(1):

find

In the output, you'll see a message similar to:

http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1

a task can set.  The rlimit defaults to 0, meaning no change in behavior by

100 means all 99 privilege levels from 1 to 99 are allowed.  CAP_SYS_NICE is
blanket permission.
