63c9480170 PM / Runtime: Use deferred_resume flag in pm_request_resume
This patch (as1307) adds a small optimization to
__pm_request_resume().  If the device is currently being suspended,
there's no need to queue a work routine to resume it.  Setting the
deferred_resume flag will suffice.  (There's also a minor improvement
to the function's code layout: An unnecessary "else" is removed.)

Also, the patch clarifies the usage of the deferred_resume flag.  It
is meaningful only while a suspend is in progress, so it should be
cleared just before a suspend starts, not just after one ends.

bb729bc98c cfq-iosched: use call_rcu() instead of doing grace period stall on queue exit
After the merge of the IO controller patches, booting on my megaraid
box ran much slower. Vivek Goyal traced it down to megaraid discovery
creating tons of devices, each suffering a grace period when they later
kill that queue (if no device is found).

So lets use call_rcu() to batch these deferred frees, instead of taking
the grace period hit for each one.

7f5620a5fc sparc: Set UTS_MACHINE correctly.
"ARCH" can be just about anything, so we shouldn't end up
with UTS_MACHINE of "sparc" in a 64-bit kernel build just
because someone set the personality using 'sparc32' or
similar.  CONFIG_SPARC64 drives the compilation and
therefore provides the definitive value, not "ARCH".

This mirrors commit 8c6531f7a9
(x86: correctly set UTS_MACHINE for "make ARCH=x86")

38938c879e Add support for GCC-4.5's __builtin_unreachable() to compiler.h (v2)
Starting with version 4.5, GCC has a new built-in function
__builtin_unreachable() that can be used in places like the kernel's
BUG() where inline assembly is used to transfer control flow.  This
eliminated the need for an endless loop in these places.

The patch adds a new macro 'unreachable()' that will expand to either
__builtin_unreachable() or an endless loop depending on the compiler
version.

Change from v1: Simplify unreachable() for non-GCC 4.5 case.

d29cecda03 mac80211: fix reorder buffer release
My patch "mac80211: correctly place aMPDU RX reorder code"
uses an skb queue for MPDUs that were released from the
buffer. I intentially didn't initialise and use the skb
queue's spinlock, but in this place forgot that the code
variant that doesn't touch the spinlock is needed.

Thanks to Christian Lamparter for quickly spotting the
bug in the backtrace Reinette reported.

f195e2bff3 m68k: ptrace fixes
This fixes the following issues in ptrace:

- when single stepping into the signal handler stop at the first insn of
  the handler
- handle non-zero stkadj when accessing pc and sr in ptregs
- correctly handle PT_SR in PTRACE_POKEUSR
- report -EIO when trying to read unknown offset in PTRACE_PEEKUSR

Additionally, the handling of the special case that PT_SR accesses a 16
bit word instead of a 32 bit word has been moved into get_reg/put_reg.
