Update recovery_offset even when external metadata is used.
The update of ->recovery_offset in sync_sbs is appropriate even then external
metadata is in use. However sync_sbs is only called when native
metadata is used.
So move that update in to the top of md_update_sb (which is the only
caller of sync_sbs) before the test on ->external.
This moves the update out of ->write_lock protection, but those fields
only need ->reconfig_mutex protection which they still have.
Also move the test on ->persistent up to where ->external is set as
for metadata update purposes they are the same.
Clear MD_CHANGE_DEVS and MD_CHANGE_CLEAN as they can only be confusing
if ->external is set or ->persistent isn't.
Finally move the update of ->utime down as it is only relevent (like
the ->events update) for native metadata.

Fix unprotected access to task credentials in waitid()
Using a program like the following:

id_t id;
siginfo_t infop;

}
to call waitid() on a stopped process results in access to the child task's
credentials without the RCU read lock being held - which may be replaced in the
meantime - eliciting the following warning:
===================================================

This is fixed by holding the RCU read lock in wait_task_continued() to ensure
that the task's current credentials aren't destroyed between us reading the
cred pointer and us reading the UID from those credentials.
Furthermore, protect wait_task_stopped() in the same way.
We don't need to keep holding the RCU read lock once we've read the UID from
the credentials as holding the RCU read lock doesn't stop the target task from
changing its creds under us - so the credentials may be outdated immediately
after we've read the pointer, lock or no lock.

Make do_execve() take a const filename pointer
Make do_execve() take a const filename pointer so that kernel_execve() compiles
correctly on ARM:
arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type
This also requires the argv and envp arguments to be consted twice, once for
the pointer array and once for the strings the array points to. This is
because do_execve() passes a pointer to the filename (now const) to
copy_strings_kernel(). A simpler alternative would be to cast the filename
pointer in do_execve() when it's passed to copy_strings_kernel().
do_execve() may not change any of the strings it is passed as part of the argv
or envp lists as they are some of them in .rodata, so marking these strings as
const should be fine.
Further kernel_execve() and sys_execve() need to be changed to match.
This has been test built on x86_64, frv, arm and mips.

AppArmor: fix task_setrlimit prototype
After rlimits tree was merged we get the following errors:

It is because AppArmor was merged in the meantime, but uses the old

This uncouples the detection of the number of backlight brightness

ARM: 6329/1: wire up sys_accept4() on ARM
sys_accept4() was added in kernel 2.6.28, but ARM was not updated
to include it. The number and types of parameters is such that
no ARM-specific processing is needed, so wiring up sys_accept4()
just requires defining __NR_accept4 and adding a direct call in
the syscall entry table.
Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original
accept4() test program, modified to define __NR_accept4 for ARM.
Using the updated unistd.h also eliminates a warning then building
glibc (2.10.2 and newer) about accept4() being unimplemented.

arch/tile: don't validate CROSS_COMPILE needlessly
With this change, the arch/tile Makefile will only check for a valid
combination of CROSS_COMPILE vs "uname -m" for a few common targets
that are typically the ones we get wrong (vmlinux, all, and modules).
The change handles the case of an empty "make" goal like "make all".

mm: fix up some user-visible effects of the stack guard page
This commit makes the stack guard page somewhat less visible to user
space. It does this by:
- not showing the guard page in /proc/<pid>/maps
It looks like lvm-tools will actually read /proc/self/maps to figure
out where all its mappings are, and effectively do a specialized
"mlockall()" in user space. By not showing the guard page as part of
the mapping (by just adding PAGE_SIZE to the start for grows-up
pages), lvm-tools ends up not being aware of it.
- by also teaching the _real_ mlock() functionality not to try to lock
the guard page.
That would just expand the mapping down to create a new guard page,
so there really is no point in trying to lock it in place.
It would perhaps be nice to show the guard page specially in
/proc/<pid>/maps (or at least mark grow-down segments some way), but
let's not open ourselves up to more breakage by user space from programs
that depends on the exact deails of the 'maps' file.
Special thanks to Henrique de Moraes Holschuh for diving into lvm-tools
source code to see what was going on with the whole new warning.
