frv: delete incorrect task prototypes causing compile fail
slub: missing test for partial pages flush work in flush_all()
fs, proc: fix ABBA deadlock in case of execution attempt of map_files/ entries
drivers/rtc/rtc-pl031.c: configure correct wday for 2000-01-01
Instead of doing the i_mode calculations at proc_fd_instantiate() time,
move them into tid_fd_revalidate(), which is where the other inode state
(notably uid/gid information) is updated too.
Otherwise we'll end up with stale i_mode information if an fd is re-used
while the dentry still hangs around. Not that anything really *cares*
(symlink permissions don't really matter), but Tetsuo Handa noticed that
the owner read/write bits don't always match the state of the
readability of the file descriptor, and we _used_ to get this right a
long time ago in a galaxy far, far away.
Besides, aside from fixing an ugly detail (that has apparently been this
way since commit 61a2878402: "proc: Remove the hard coded inode
numbers" in 2006), this removes more lines of code than it adds. And it
just makes sense to update i_mode in the same place we update i_uid/gid.
Al Viro correctly points out that we could just do the inode fill in the
inode iops ->getattr() function instead. However, that does require
somewhat slightly more invasive changes, and adds yet *another* lookup
of the file descriptor. We need to do the revalidate() for other
reasons anyway, and have the file descriptor handy, so we might as well
fill in the information at this point.

(&sb->s_type->i_mutex_key#8){+.+.+.}, at: do_lookup+0x267/0x2b1
but task is already holding lock:
(&sig->cred_guard_mutex){+.+.+.}, at: prepare_bprm_creds+0x2d/0x69
which lock already depends on the new lock.

This is because prepare_bprm_creds grabs task->signal->cred_guard_mutex
and when do_lookup happens we try to grab task->signal->cred_guard_mutex
again in lock_trace.
Fix it using plain ptrace_may_access() helper in proc_map_files_lookup()
and in proc_map_files_readdir() instead of lock_trace(), the caller must
be CAP_SYS_ADMIN granted anyway.

moved over to the gate_vma mechanism:

With commit f9d4861f ("ARM: 7294/1: vectors: use gate_vma for vectors user

proc: fix mount -t proc -o AAA
The proc_parse_options() call from proc_mount() runs only once at boot
time. So on any later mount attempt, any mount options are ignored
because ->s_root is already initialized.
As a consequence, "mount -o <options>" will ignore the options. The
only way to change mount options is "mount -o remount,<options>".
To fix this, parse the mount options unconditionally.

Git commit a25cac5198 "proc: Consider NO_HZ when printing idle and
iowait times" changes the code for /proc/stat to use get_cpu_idle_time_us
and get_cpu_iowait_time_us if the system is running with nohz enabled.
For architectures which define arch_idle_time (currently s390 only)
this is a change for the worse. The result of arch_idle_time is supposed
to be the exact sleep time of the target cpu and should be used instead
of the value kept by the scheduler.

Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

Pull sysctl updates from Eric Biederman:
- Rewrite of sysctl for speed and clarity.
Insert/remove/Lookup in sysctl are all now O(NlogN) operations, and
are no longer bottlenecks in the process of adding and removing
network devices.
sysctl is now focused on being a filesystem instead of system call
and the code can all be found in fs/proc/proc_sysctl.c. Hopefully
this means the code is now approachable.
Much thanks is owed to Lucian Grinjincu for keeping at this until
something was found that was usable.
- The recent proc_sys_poll oops found by the fuzzer during hibernation
is fixed.

The namespace cleanup path leaks a dentry which holds a reference count
on a network namespace. Keeping that network namespace from being freed
when the last user goes away. Leaving things like vlan devices in the
leaked network namespace.
If you use ip netns add for much real work this problem becomes apparent
pretty quickly. It light testing the problem hides because frequently
you simply don't notice the leak.
Use d_set_d_op() so that DCACHE_OP_* flags are set correctly.
This issue exists back to 3.0.

Process accounting applications as top, ps visit some files under

This patch adds
- seq_put_decimal_ll() for signed values.
- allow delimiter == 0.
- convert seq_printf() to seq_put_decimal_ull/ll in /proc/stat, statm.

On a typical 16 cpus machine, "cat /proc/stat" gives more than 4096 bytes,
and is slow :
# strace -T -o /tmp/STRACE cat /proc/stat | wc -c
5826
# grep "cpu " /tmp/STRACE
read(0, "cpu 1949310 19 2144714 12117253"..., 32768) = 5826 <0.001504>
Thats partly because show_stat() must be called twice since initial
buffer size is too small (4096 bytes for less than 32 possible cpus)
Fix this by :
1) Taking into account nr_irqs in the initial buffer sizing.
2) Using ksize() to allow better filling of initial buffer.

Protect code accessing ctl_table by grabbing the header with grab_header()

is called in entries created by modules: currently only hostname and
domainname support poll(), but this bug may be triggered when/if modules
use it and if user called poll() in a file that doesn't support it.
