ARM: OMAP4: EMIF: implementation of errata i735 for PM timer

EMIF Power Management timer for Self Refresh will put the external SDRAM
in Self Refresh mode after the EMIF is idle for number of DDR clock cycles
that is set with REG_SR_TIM. The minimal value starts at 16 cycles.
However due to Errata i735, the minimal value is 512 DDR cycles as it is
required at OPP100 frequency.

bcmdhd: workaround broken AC video queue in IBSS mode

The BCM4330 has problems with the WME video (AC_VI) queue in IBSS mode. If we
put packets into this AC, the symptoms are excessive RTS/CTS, most packets get
lost and the device get's stuck and no more packets can be sent, even on other
queues.

Since the AC queue selection happens in the firmware based on the DSCP priority
and we don't know a way to configure this in the driver the workaround is to
simply downgrade all packets which would go into AC_VI (priority 4 and 5, TOS
0x80 and 0xa0) to AC_BE (priority 3 "Excellent Effort"). It's not pretty but
makes the device usable.

Asynchronous I/O latency to a solid-state disk greatly increased
between the 2.6.32 and 3.0 kernels. By removing the plug from
do_io_submit(), we observed a 34% improvement in the I/O latency.

Unfortunately, at this level, we don't know if the request is to
a rotating disk or not.

mm/page-writeback.c: adjust dirty writeback for previously introduced lower vmalloc

Ever since vmalloc=182M, all available RAM is low memory. By leaving the
dirty ratios unchanged, this resulted in a massive increase in dirtyable
memory. The new values adjust the ratios to achieve roughly the same amount of
dirtyable memory in megabytes as before.
block: strict rq_affinity

Some systems benefit from completions always being steered to the strict
requester cpu rather than the looser "per-socket" steering that
blk_cpu_to_group() attempts by default. This is because the first
CPU in the group mask ends up being completely overloaded with work,
while the others (including the original submitter) has power left
to spare.

Allow the strict mode to be set by writing '2' to the sysfs control
file. This is identical to the scheme used for the nomerges file,
where '2' is a more aggressive setting than just being turned on.
