Stub out vm_get_page_prot() if there's no MMU.
This was added by commit 804af2cf6e7a ("[AGPGART] remove private page
protection map") and is used in commit c07fbfd17e61 ("fbmem: VM_IO set,
but not propagated") in the fbmem video driver, but the function doesn't
exist on NOMMU, resulting in an undefined symbol at link time.

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.

There were some new formats added in commit 15c0cee6c809 "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.

Setting the task state here may cause us to miss the wake up from
kthread_stop(), so we need to recheck kthread_should_stop() or risk
sleeping forever in the following schedule().
Symptom was an indefinite hang on an NFSv4 mount. (NFSv4 may create
multiple mounts in a temporary namespace while traversing the mount
path, and since the temporary namespace is immediately destroyed, it may
end up destroying a mount very soon after it was created, possibly
making this race more likely.)

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/)

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
and actually make the code a little easier to understand.

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.

if_sdio's lbs_helper_name and lbs_fw_name against sysfs changes)
introduced new fields into the if_sdio_card structure. It caused
missalignment of the if_sdio_card.buffer field and failure at driver

Fixes a regression caused by 21edad32205e97dc7ccb81a85234c77e760364c8
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.

The reason of this hang was a race condition: when the flusher thread is
forking a bdi thread, we use 'kthread_run()', so we run it _before_ we make it
visible in 'bdi->wb.task'. The bdi thread runs, does all works, and goes sleep.
'bdi->wb.task' is still NULL. And this is a dangerous time window.
If at this time someone queues a work for this bdi, he does not see the bdi
thread and wakes up the forker thread instead! But the forker has already
forked this bdi thread, but just did not make it visible yet!
The result is that we lose the wake up event for this bdi thread and the NFS4
code waits forever.
To fix the problem, we should use 'ktrhead_create()' for creating bdi threads,
then make them visible in 'bdi->wb.task', and only after this wake them up.
This is exactly what this patch does.

'long unsigned int', but argument 12 has type 'unsigned int'
And removes the useless parens and white space.

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.
