Similar to ocfs2_write_end_nolock() which is metioned at commit
136f49b917 ("ocfs2: fix journal commit deadlock"), we should unlock
pages before ocfs2_commit_trans() in ocfs2_convert_inline_data_to_extents.
Otherwise, it will cause a deadlock with journal commit threads.

Commit e9fd702a58 ("audit: convert audit watches to use fsnotify
instead of inotify") broke handling of renames in audit. Audit code
wants to update inode number of an inode corresponding to watched name
in a directory. When something gets renamed into a directory to a
watched name, inotify previously passed moved inode to audit code
however new fsnotify code passes directory inode where the change
happened. That confuses audit and it starts watching parent directory
instead of a file in a directory.
This can be observed for example by doing:
cd /tmp
touch foo bar
auditctl -w /tmp/foo
touch foo
mv bar foo
touch foo
In audit log we see events like:
type=CONFIG_CHANGE msg=audit(1423563584.155:90): auid=1000 ses=2 op="updated rules" path="/tmp/foo" key=(null) list=4 res=1
...
type=PATH msg=audit(1423563584.155:91): item=2 name="bar" inode=1046884 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=DELETE
type=PATH msg=audit(1423563584.155:91): item=3 name="foo" inode=1046842 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=DELETE
type=PATH msg=audit(1423563584.155:91): item=4 name="foo" inode=1046884 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=CREATE
...
and that's it - we see event for the first touch after creating the
audit rule, we see events for rename but we don't see any event for the
last touch. However we start seeing events for unrelated stuff
happening in /tmp.
Fix the problem by passing moved inode as data in the FS_MOVED_FROM and
FS_MOVED_TO events instead of the directory where the change happens.
This doesn't introduce any new problems because noone besides
audit_watch.c cares about the passed value:
fs/notify/fanotify/fanotify.c cares only about FSNOTIFY_EVENT_PATH events.
fs/notify/dnotify/dnotify.c doesn't care about passed 'data' value at all.
fs/notify/inotify/inotify_fsnotify.c uses 'data' only for FSNOTIFY_EVENT_PATH.
kernel/audit_tree.c doesn't care about passed 'data' at all.
kernel/audit_watch.c expects moved inode as 'data'.

Currently FAN_ONDIR is always set on a mark's ignored mask when the
event mask is extended without FAN_MARK_ONDIR being set. This may
result in events for directories being ignored unexpectedly for call
sequences like
fanotify_mark(fd, FAN_MARK_ADD, FAN_OPEN | FAN_ONDIR , AT_FDCWD, "dir");
fanotify_mark(fd, FAN_MARK_ADD, FAN_CLOSE, AT_FDCWD, "dir");
Also FAN_MARK_ONDIR is only honored when adding events to a mark's mask,
but not for event removal. Fix both issues by not setting FAN_ONDIR
implicitly on the ignore mask any more. Instead treat FAN_ONDIR as any
other event flag and require FAN_MARK_ONDIR to be set by the user for
both event mask and ignore mask. Furthermore take FAN_MARK_ONDIR into
account when set for event removal.

The __asmeq macro is used inside inline asm statements to ensure that
register asm variables that explicitly specify a register are mapped
correctly onto those registers when used in inline asm input and output
constraints. However, the string based matching fails to take into
account that 'fp' is often referred to as 'r11' and 'ip' is often
referred to as 'r12', (e.g., by clang), causing false negatives.
Fix this by making __asmeq consider the ("fp","r11"), ("r11","fp"),
("ip","r12") and ("r12","ip") cases specifically.

show_cacheinfo() needs to access the cacheinfo structure of any online
cpu. This was done with using smp_processor_id() as in index while in
preemtible context.
This means the cpu could be offline and the data be gone when it would
be accessed.
Better use any online cpu address and protect the data by get_online_cpus()
and put_online_cpus().

There is a superfluous '*' in the definition of kprobe_decode_insn_t
which on older versions of GCC (4.2.4) causes the compilation error:
In file included from arch/arm/probes/kprobes/core.c:37:
arch/arm/probes/kprobes/core.h:43: error: '[*]' not allowed in other than a declaration
Fix this by removing the unneeded character.
