a118b5f339 OMAP3: GPIO fixes for off-mode
Off mode is now using the omap2 retention fix code for scanning GPIOs
during off-mode transitions. All the *non_wakeup_gpios variables
are now used for off-mode transition tracking on OMAP3. This patch fixes
cases where GPIO state changes are missed during off-mode.

1c6fe0364f cpuidle: Fix incorrect optimization
commit 672917dcc7 ("cpuidle: menu governor: reduce latency on exit")
added an optimization, where the analysis on the past idle period moved
from the end of idle, to the beginning of the new idle.

Unfortunately, this optimization had a bug where it zeroed one key
variable for new use, that is needed for the analysis.  The fix is
simple, zero the variable after doing the work from the previous idle.

During the audit of the code that found this issue, another issue was
also found; the ->measured_us data structure member is never set, a
local variable is always used instead.

1176568de7 md: restore ability of spare drives to spin down.
Some time ago we stopped the clean/active metadata updates
from being written to a 'spare' device in most cases so that
it could spin down and say spun down.  Device failure/removal
etc are still recorded on spares.

However commit 51d5668cb2 broke this 50% of the time,
depending on whether the event count is even or odd.
The change log entry said:

   This means that the alignment between 'odd/even' and
    'clean/dirty' might take a little longer to attain,

how ever the code makes no attempt to create that alignment, so it
could take arbitrarily long.

So when we find that clean/dirty is not aligned with odd/even,
force a second metadata-update immediately.  There are already cases
where a second metadata-update is needed immediately (e.g. when a
device fails during the metadata update).  We just piggy-back on that.

03b1930efd V4L/DVB: saa7146: fix regression of the av7110/budget-av driver
An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.

Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.

The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
of hardware makes this hard to do, though. I hope to get hold of some
hexium cards and then I can try to improve the framework to prevent
this from happening again.

ee84b8243b rcu: create rcu_my_thread_group_empty() wrapper
Some RCU-lockdep splat repairs need to know whether they are running
in a single-threaded process.  Unfortunately, the thread_group_empty()
primitive is defined in sched.h, and can induce #include hell.  This
commit therefore introduces a rcu_my_thread_group_empty() wrapper that
is defined in rcupdate.c, thus avoiding the need to include sched.h
everywhere.

3274c5707c microblaze: Optimize CACHE_LOOP_LIMITS and CACHE_RANGE_LOOP macros
1. Remove CACHE_ALL_LOOP2 macro because it is identical to CACHE_ALL_LOOP
2. Change BUG_ON to WARN_ON
3. Remove end aligned from CACHE_LOOP_LIMITS.
C implementation do not need aligned end address and ASM code do aligned
in their macros
4. ASM optimized  CACHE_RANGE_LOOP_1/2 macros needs to get aligned end address.
Because end address is compound from start + size, end address is the first address
which is exclude.

Here is the corresponding code which describe it.
+       int align = ~(line_length - 1);
+       end = ((end & align) == end) ? end - line_length : end & align;

a) end is aligned:
it is necessary to subtruct line length because we don't want to work with
next cacheline
b) end address is not aligned:
Just align it to be ready for ASM code.

598acab44d microblaze: Define correct L1_CACHE_SHIFT value
Microblaze cacheline length is configurable and current cpu
uses two cacheline length 4 and 8.

We are taking conservative maximum value to be sure that cacheline
alignment is satisfied for all cases.

Here is the calculation for cacheline lenght 8  32bit=4Byte values
which is corresponding with SHIFT 5.

de925d9d3b microblaze: Fix kmalloc alignment on non-coherent DMA platforms
Based on PowerPC patche 52142e756e

PowerPC description:
On platforms doing non-coherent DMA (4xx, 8xx, ...), it's important
that the kmalloc minimum alignment is set to the cache line size, to
avoid sharing cache lines between different objects, so that DMA to
one of the objects doesn't corrupt the other.

f1525765fb microblaze: Fix consistent code
This patch fix consistent code which had problems with consistent_free
function.
I am not sure if we need to call flush_tlb_all after it but it keeps
tlbs synced.
I added noMMU and MMU version together.

Uncached shadow feature is not tested.
