Greg Kroah-Hartman	206a81c184	lzo: properly check for overruns ... The lzo decompressor can, if given some really crazy data, possibly overrun some variable types. Modify the checking logic to properly detect overruns before they happen. Reported-by: "Don A. Bailey" <donb@securitymouse.com> Tested-by: "Don A.

Markus F.X.J. Oberhumer	8b975bd3f9	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.

Markus F.X.J. Oberhumer	b6bec26cea	lib/lzo: Rename lzo1x_decompress.c to lzo1x_decompress_safe.c ... Rename the source file to match the function name and thereby also make room for a possible future even slightly faster "non-safe" decompressor version. Signed-off-by: Markus F.X.J.
