No idea why it turned world non-readable, fixed.

But I am afraid I did not find any real situation where these patches
really helps (AND not cause problems with different pattern).
See also discussion on dm-devel list, I still think generic
kernel workqueues should be used to provide such parallelization and
we should not duplicate code in dm-crypt...

My suggestion is that using AES-NI extension helps much more with
the current upstream code than anything else (for AES, obviously).
