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.Signed-off-by: Markus F.X.J. Oberhumer

Add some casts to the LZO compression algorithm after they were removed
during cleanup and shouldn't have been.Signed-off-by: Richard Purdie

This is a hybrid version of the patch to add the LZO1X compression
algorithm to the kernel. Nitin and myself have merged the best parts of
the various patches to form this version which we're both happy with (and
are jointly signing off).The performance of this version is equivalent to the original minilzo code
it was based on. Bytecode comparisons have also been made on ARM, i386 and
x86_64 with favourable results.There are several users of LZO lined up including jffs2, crypto and reiser4
since its much faster than zlib.Signed-off-by: Nitin Gupta
