If mic detect is left enabled and the WM8903 detects a status change,
the WM8903 driver will make a callback against the free()d jack, which
will cause a crash.
This problem can be triggered by fully initializing an audio card, then
removing and re-inserting the machine driver module.

Function led_set_software_blink() assumes that blink timer is still running,
but commit 488bc35bf4 introduced disabling

Correct led_software_blink():
1) remove protection against reprogramming blink timer to the same values,
because it only disables blinking now,
2) remove unnecessary call to led_stop_software_blink().

The assembler entry code calls directly to the syscall_trace_enter() and

When building for non-MMU based classic 68k CPU types (like the 68328 for
example) you get a compilation error:
CC arch/m68k/kernel/time.o
arch/m68k/kernel/time.c:91:5: error: redefinition of ‘arch_gettimeoffset’
include/linux/time.h:145:19: note: previous definition of ‘arch_gettimeoffset’ was here
The arch_gettimeoffset() code is included when building for these CPU types,
but it shouldn't be. Those machine types do not have
CONFIG_ARCH_USES_GETTIMEOFFSET set.
The fix is simply to conditionally include the arch_gettimeoffset() code on
that same config setting that specifies its use or not.

lpc_eth does a copy of transmitted skbs to DMA area, without checking

The logic was checking the sizeof the structure being allocated to
determine whether an alignment fixup was required. This isn't right;
what we actually care about is the alignment of the actual pointer that's
about to be returned. This became an issue recently because struct
edac_mc_layer has a size that is not zero modulo eight, so we were
taking the correctly-aligned pointer and forcing it to be misaligned.
On Tile this caused an alignment exception.

Some edac drivers register themselves as mce decoders via
notifier_chain. But in current notifier_chain implementation logic,
it doesn't accept same notifier registered twice. If so, it will be
wrong when adding/removing the element from the list. For example,
on one SandyBridge platform, remove module sb_edac and then trigger
one error, it will hit oops because it has no mce decoder registered
but related notifier_chain still points to an invalid callback
function. Here is an example:

Merge RCU fixes from Paul E. McKenney:
" This series has four patches, the major point of which is to eliminate
some slowdowns (including boot-time slowdowns) resulting from some
RCU_FAST_NO_HZ changes. The issue with the changes is that posting timers
from the idle loop has no effect if the CPU has entered dyntick-idle
mode because the CPU has already computed its wakeup time, and posting
a timer does not cause it to be recomputed. The short-term fix is for
RCU to precompute the timeout value so that the CPU's calculation is
correct. "
