it's not needed anymore; we used to, back when we had to do
mount_subtree() by hand, complete with put_mnt_ns() in it.
No more... Apparmor didn't need it since the __d_path() fix.

tomoyo/realpath.c needs exactly one include - that of common.h. It pulls
everything the thing needs, without doing ridiculous garbage such as trying
to include ../../fs/internal.h. If that alone doesn't scream "layering
violation", I don't know what does; and these days it's all for nothing,
since it fortunately does not use any symbols defined in there...

a) mount --move is checking that ->mnt_parent is non-NULL before
looking if that parent happens to be shared; ->mnt_parent is never
NULL and it's not even an misspelled !mnt_has_parent()
b) pivot_root open-codes is_path_reachable(), poorly.
c) so does path_is_under(), while we are at it.

vfsmounts have ->mnt_parent pointing either to a different vfsmount
or to itself; it's never NULL and termination condition in loops
traversing the tree towards root is mnt == mnt->mnt_parent. At least
one place (see the next patch) is confused about what's going on;
let's add an explicit helper checking it right way and use it in
all places where we need it. Not that there had been too many,
but...

No need to duplicate them in both callers; make it return
ERR_PTR(-ENOMEM) on allocation failure instead of NULL and
it'll be able to report rpc_lookup_cred() failures just
fine. Callers are much happier that way...

This reverts commit c0afabd3d553c521e003779c127143ffde55a16f.
It causes failures on Toshiba laptops - instead of disabling the alarm,
it actually seems to enable it on the affected laptops, resulting in
(for example) the laptop powering on automatically five minutes after
shutdown.
There's a patch for it that appears to work for at least some people,
but it's too late to play around with this, so revert for now and try
again in the next merge window.

Commit 1e39f384bb01 ("evm: fix build problems") makes the stub version
of security_old_inode_init_security() return 0 when CONFIG_SECURITY is
not set.
But that makes callers such as reiserfs_security_init() assume that
security_old_inode_init_security() has set name, value, and len
arguments properly - but security_old_inode_init_security() left them
uninitialized which then results in interesting failures.
Revert security_old_inode_init_security() to the old behavior of
returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this
just fine.
[ Also fixed the S_PRIVATE(inode) case of the actual non-stub
security_old_inode_init_security() function to return EOPNOTSUPP
for the same reason, as pointed out by Mimi Zohar.
It got incorrectly changed to match the new function in commit
fb88c2b6cbb1: "evm: fix security/security_old_init_security return
code". - Linus ]

It was found (by Sasha) that if you use a futex located in the gate
area we get stuck in an uninterruptible infinite loop, much like the
ZERO_PAGE issue.
While looking at this problem, PeterZ realized you'll get into similar
trouble when hitting any install_special_pages() mapping. And are there
still drivers setting up their own special mmaps without page->mapping,
and without special VM or pte flags to make get_user_pages fail?
In most cases, if page->mapping is NULL, we do not need to retry at all:
Linus points out that even /proc/sys/vm/drop_caches poses no problem,
because it ends up using remove_mapping(), which takes care not to
interfere when the page reference count is raised.
But there is still one case which does need a retry: if memory pressure
called shmem_writepage in between get_user_pages_fast dropping page
table lock and our acquiring page lock, then the page gets switched from
filecache to swapcache (and ->mapping set to NULL) whatever the refcount.
Fault it back in to get the page->mapping needed for key->shared.inode.

The sanity check (timeout < 0) never works; the dividend is unsigned
and so is the division, which should have been a signed division.
long timeout = (ct->timeout.expires - jiffies) / HZ;
if (timeout < 0)
timeout = 0;
This patch converts the time values to signed for the division.

Commit 2a95ea6c0d129b4 ("procfs: do not overflow get_{idle,iowait}_time
for nohz") did not take into account that one some architectures jiffies
and cputime use different units.
This causes get_idle_time() to return numbers in the wrong units, making
the idle time fields in /proc/stat wrong.
Instead of converting the usec value returned by
get_cpu_{idle,iowait}_time_us to units of jiffies, use the new function
usecs_to_cputime64 to convert it to the correct unit of cputime64_t.

commit 8aacc9f550 ("mm/mempolicy.c: fix pgoff in mbind vma merge") is the
slightly incorrect fix.
Why? Think following case.
1. map 4 pages of a file at offset 0
[0123]
2. map 2 pages just after the first mapping of the same file but with
page offset 2
[0123][23]
3. mbind() 2 pages from the first mapping at offset 2.
mbind_range() should treat new vma is,
[0123][23]
|23|
mbind vma
but it does
[0123][23]
|01|
mbind vma
Oops. then, it makes wrong vma merge and splitting ([01][0123] or similar).
This patch fixes it.

The new iso bandwidth calculation code accidentally has broken support
for bulk mode cameras. This has broken the following drivers:
finepix, jeilinj, ovfx2, ov534, ov534_9, se401, sq905, sq905c, sq930x,
stv0680, vicam.
Thix patch fixes this. Fix tested with: se401, sq905, sq905c, stv0680 & vicam
cams.

Ceph attempts to use the dcache to satisfy negative lookups and readdir
when the entire directory contents are in cache. Disable this behavior
until lingering bugs in this code are shaken out; we'll re-enable these
hooks once things are fully stable.

Commit 5e081591 "block: warn if tag is greater than real_max_depth"
cleaned up blk_queue_end_tag() to warn when the tag is truly invalid
(greater than real_max_depth). However, it changed behavior in the tag <
max_depth case to not end the request. Leading to triggering of
BUG_ON(blk_queued_rq(rq)) in the request completion path:
http://marc.info/?l=linux-kernel&m=132204370518629&w=2
In order to allow blk_queue_resize_tags() to shrink the tag space
blk_queue_end_tag() must always complete tags with a value less than
real_max_depth regardless of the current max_depth. The comment about
"handling the shrink case" seems to be what prompted changes in this
space, so remove it and BUG on all invalid tags (made even simpler by
Matthew's suggestion to use an unsigned compare).

Following is happened when CONFIG_CPU_FREQ_S3C24XX_DEBUGFS
is selected without building of s3c2410-iotiming.c file:
arch/arm/mach-s3c2440/built-in.o:(.data+0x38c): undefined reference to `s3c2410_iotiming_debugfs
Basically, the CONFIG_S3C2410_IOTIMING is not selected for
MACH_MINI2440. Because the s3c2410-iotiming.c is not ever
compiled and enabling CONFIG_CPU_FREQ_S3C24XX_DEBUGFS option
caused undefined reference to s3c2410_iotiming_debugfs()
defined in that file. The s3c2410_iotiming_debugfs defined
as NULL for this case.
