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" * tag 'lzo-update-signature-20130226' of git://github.com/markus-oberhumer/linux: crypto: testmgr - update LZO compression test vectors lib/lzo: Update LZO compression to current upstream version lib/lzo: Rename lzo1x_decompress.c to lzo1x_decompress_safe.c
