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"

Merge branch '3.8/misc' into 3.8/master
Revert "Merge remote-tracking branch 'github/3.8/zswap' into 3.8/master"

This reverts commit 636753a4bfe5f5e013ce22684b99e42a454f0804, reversing
changes made to 7a69e9a8db95dd13ff1beb7ad8cdf3c4edac4a32.

zcache (CONFIG_ZCACHE2) is already mainline and provides both compressed
cache *and* compressed swap, so zswap really isn't that interesting.
