Merge tag 'lzo-update-signature-20130226' of git://github.com/markus-oberhumer/linux
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"
