Merge branch 'akpm' (aka "Andrew's patch-bomb") 

Andrew elucidates:
 - First installmeant of MM.  We have a HUGE number of MM patches this
   time.  It's crazy.
 - MAINTAINERS updates
 - backlight updates
 - leds
 - checkpatch updates
 - misc ELF stuff
 - rtc updates
 - reiserfs
 - procfs
 - some misc other bits

What: Attribute for calibrating ST-Ericsson AB8500 Real Time Clock
Date: Oct 2011
KernelVersion: 3.0
Contact: Mark Godfrey <mark.godfrey@stericsson.com>
Description: The rtc_calibration attribute allows the userspace to
calibrate the AB8500.s 32KHz Real Time Clock.
Every 60 seconds the AB8500 will correct the RTC's value
by adding to it the value of this attribute.
The range of the attribute is -127 to +127 in units of
30.5 micro-seconds (half-parts-per-million of the 32KHz clock)
Users: The /vendor/st-ericsson/base_utilities/core/rtc_calibration
daemon uses this interface.

4.1 Mount options
---------------------
The following mount options are supported:
hidepid= Set /proc/<pid>/ access mode.
gid= Set the group authorized to learn processes information.
hidepid=0 means classic mode - everybody may access all /proc/<pid>/ directories
(default).
hidepid=1 means users may not access any /proc/<pid>/ directories but their
own. Sensitive files like cmdline, sched*, status are now protected against
other users. This makes it impossible to learn whether any user runs
specific program (given the program doesn't reveal itself by its behaviour).
As an additional bonus, as /proc/<pid>/cmdline is unaccessible for other users,
poorly written programs passing sensitive information via program arguments are
now protected against local eavesdroppers.
hidepid=2 means hidepid=1 plus all /proc/<pid>/ will be fully invisible to other
users. It doesn't mean that it hides a fact whether a process with a specific
pid value exists (it can be learned by other means, e.g. by "kill -0 $PID"),
but it hides process' uid and gid, which may be learned by stat()'ing
/proc/<pid>/ otherwise. It greatly complicates an intruder's task of gathering
information about running processes, whether some daemon runs with elevated
privileges, whether other user runs some sensitive program, whether other users
run any program at all, etc.
gid= defines a group authorized to learn processes information otherwise
prohibited by hidepid=. If you use some daemon like identd which needs to learn
information about processes information, just add identd to this group.

be intentionally kept free (and hence protected) by the
buddy allocator. Bigger value increase the probability
of catching random memory corruption, but reduce the
amount of memory for normal system use. The maximum
possible value is MAX_ORDER/2. Setting this parameter
to 1 or 2 should be enough to identify most random
memory corruption problems caused by bugs in kernel or
driver code when a CPU writes to (or reads from) a
random memory location. Note that there exists a class
of memory corruptions problems caused by buggy H/W or
F/W or by drivers badly programing DMA (basically when
memory is written at bus level and the CPU MMU is
bypassed) which are not detectable by
CONFIG_DEBUG_PAGEALLOC, hence this option will not help
tracking down these problems.
