As this relates to my work on zcache, I just tested these patches on PPC64 and
they cause the LZO crypto module to fail its self-test:

[    0.521137] alg: comp: Compression test 1 failed for lzo-generic: output len = 62

I built the exact same kernel for x86_64 and all is fine.  I suspect an endianness
related bug, but I haven't looked at the code that closely yet.

Any ideas?  I'd be happy to test any potential fixes.
