disable frame pointer and crc for better overall performance
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.

block: recursive merge requests

In a workload, thread 1 accesses a, a+2, ..., thread 2 accesses a+1, a+3,....
When the requests are flushed to queue, a and a+1 are merged to (a, a+1), a+2
and a+3 too to (a+2, a+3), but (a, a+1) and (a+2, a+3) aren't merged.

If we do recursive merge for such interleave access, some workloads throughput
get improvement. A recent worload I'm checking on is swap, below change
boostes the throughput around 5% ~ 10%.

block: Reserve only one queue tag for sync IO if only 3 tags are available

In case a device has three tags available we still reserve two of them
for sync IO. That leaves only a single tag for async IO such as
writeback from flusher thread which results in poor performance.

Allow async IO to consume two tags in case queue has three tag availabe
to get a decent async write performance.

This patch improves streaming write performance on a machine with such disk
from ~21 MB/s to ~52 MB/s. Also postmark throughput in presence of
streaming writer improves from 8 to 12 transactions per second so sync
IO doesn't seem to be harmed in presence of heavy async writer.

lib/lzo: Update LZO compression to current upstream version

This commit updates the kernel LZO code to the current upsteam version
which features a significant speed improvement - benchmarking the Calgary
and Silesia test corpora typically shows a doubled performance in
both compression and decompression on modern i386/x86_64/powerpc machines.

lib:lzo: updated LZO libs

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b0af9cd9aab60ceb17d3ebabb9fdf4ff0a99cf50

Pull LZO compression update from Markus Oberhumer:
 "Summary:
  ========

  Update the Linux kernel LZO compression and decompression code to the
  current upstream version which features significant performance
  improvements on modern machines.

  Some *synthetic* benchmarks:
  ============================

    x86_64 (Sandy Bridge), gcc-4.6 -O3, Silesia test corpus, 256 kB block-size:

                     compression speed   decompression speed

    LZO-2005    :         150 MB/sec          468 MB/sec
    LZO-2012    :         434 MB/sec         1210 MB/sec

    i386 (Sandy Bridge), gcc-4.6 -O3, Silesia test corpus, 256 kB block-size:

                     compression speed   decompression speed

    LZO-2005    :         143 MB/sec          409 MB/sec
    LZO-2012    :         372 MB/sec         1121 MB/sec

    armv7 (Cortex-A9), Linaro gcc-4.6 -O3, Silesia test corpus, 256 kB block-size:

                     compression speed   decompression speed

    LZO-2005    :          27 MB/sec           84 MB/sec
    LZO-2012    :          44 MB/sec          117 MB/sec
  **LZO-2013-UA :          47 MB/sec          167 MB/sec

  Legend:

    LZO-2005    : LZO version in current 3.8 kernel (which is based on
                     the LZO 2.02 release from 2005)
    LZO-2012    : updated LZO version available in linux-next
  **LZO-2013-UA : updated LZO version available in linux-next plus experimental
                     ARM Unaligned Access patch. This needs approval
                     from some ARM maintainer ist NOT YET INCLUDED."

Andrew Morton <akpm@linux-foundation.org> acks it and says:
 "There's a new LZ4 on the block which is even faster than the sped-up
  LZO, but various filesystems and things use LZO"

redisable frame buffer
begin modifications of omap2 frequency tables,changes are as follows:
1:modification of available gpu voltages,we only use two speeds,therefore we only should define 2 voltages
2:modification of opp addreeses to allow for easier frequency adding in the future (soon)
3:correct all opp addresess to use new opp names,including inside trim
4:overclock the l3 cache
