This was added by commit 804af2cf6e ("[AGPGART] remove private page

but not propagated") in the fbmem video driver, but the function doesn't

f18194275c mm: fix hang on anon_vma->root->lock
After several hours, kbuild tests hang with anon_vma_prepare() spinning on
a newly allocated anon_vma's lock - on a box with CONFIG_TREE_PREEMPT_RCU=y
(which makes this very much more likely, but it could happen without).

The ever-subtle page_lock_anon_vma() now needs a further twist: since
anon_vma_prepare() and anon_vma_fork() are liable to change the ->root
of a reused anon_vma structure at any moment, page_lock_anon_vma()
needs to check page_mapped() again before succeeding, otherwise
page_unlock_anon_vma() might address a different root->lock.

7a28826ac7 ALSA: pcm: add more format names
There were some new formats added in commit 15c0cee6c8 "ALSA: pcm:
Define G723 3-bit and 5-bit formats".  That commit increased
SNDRV_PCM_FORMAT_LAST as well.  My concern is that there are a couple
places which do:

        for (i = 0; i < SNDRV_PCM_FORMAT_LAST; i++) {
                if (dummy->pcm_hw.formats & (1ULL << i))
                        snd_iprintf(buffer, " %s", snd_pcm_format_name(i));
        }

I haven't tested these but it looks like if "i" were equal to
SNDRV_PCM_FORMAT_G723_24 or higher then we might read past the end of
the array.

c34186ed00 net/ipv4: Eliminate kstrdup memory leak
The string clone is only used as a temporary copy of the argument val
within the while loop, and so it should be freed before leaving the
function.  The call to strsep, however, modifies clone, so a pointer to the
front of the string is kept in saved_clone, to make it possible to free it.

The sematic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

The fsnotify main loop has 2 bools which indicated if we processed the
inode or vfsmount mark in that particular pass through the loop.  These
bool can we replaced with the inode_group and vfsmount_group variables

f72adfd540 fsnotify: fix list walk order
Marks were stored on the inode and vfsmonut mark list in order from
highest memory address to lowest memory address.  The code to walk those
lists thought they were in order from lowest to highest with
unpredictable results when trying to match up marks from each.  It was
possible that extra events would be sent to userspace when inode
marks ignoring events wouldn't get matched with the vfsmount marks.

This problem only affected fanotify when using both vfsmount and inode
marks simultaneously.

The commit 886275ce41 (param: lock

introduced new fields into the if_sdio_card structure. It caused
missalignment of the if_sdio_card.buffer field and failure at driver
load time:

93c3fe40c2 eCryptfs: Fix encrypted file name lookup regression
Fixes a regression caused by 21edad3220

When file name encryption was enabled, ecryptfs_lookup() failed to use
the encrypted and encoded version of the upper, plaintext, file name
when performing a lookup in the lower file system. This made it
impossible to lookup existing encrypted file names and any newly created
files would have plaintext file names in the lower file system.

5225c45899 perf: Initialize callchains roots's childen hits
Each histogram entry has a callchain root that stores the
callchain samples. However we forgot to initialize the
tracking of children hits of these roots, which then got
random values on their creation.

The root children hits is multiplied by the minimum percentage
of hits provided by the user, and the result becomes the minimum
hits expected from children branches. If the random value due
to the uninitialization is big enough, then this minimum number
of hits can be huge and eventually filter every children branches.

The end result was invisible callchains. All we need to
fix this is to initialize the children hits of the root.

08f2e669a8 drm: fix regression in drm locking since BKL removal.
This locking path needs proper auditing but probably too late for changes at this point for 2.6.36, so lets go with the quick fix, which is to drop the lock around schedule.

12acd90f0b drm/radeon/kms: remove stray radeon_i2c_destroy
I missed this one in the i2c unification patch.  This
is handled in the core radeon i2c code now.

7521473305 drm: mm: fix range restricted allocations
With the code cleanup in

7a6b2896f2 is the first bad commit

    drm_mm: extract check_free_mm_node

I've botched up the range-restriction checks. The result is usually
an X server dying with SIGBUS in libpixman (software fallback rendering).
Change the code to adjust the start and end for range restricted
allocations. IMHO this even makes the code a bit clearer.

These days the headers we use are in glibc.  If those are too old, you can
add the -I lines to get the kernel headers.
