Indeed I've done a pretty ridiculous amount of benchmarking, and the
x86_64 numbers are included in those commits because they're pretty
straightforward to show. The performance is also better on
arm1176,cortex-a7,8,9,15,53,73. On mips, as well, performance is
better, since there wasn't any optimized code there at all. Early
versions of this patchset included a regression on cortex-a7, which
was particularly problematic because Eric Biggers recent fscrypt work
requires fast chacha on that hardware, but this v6 (and the future v7)
contain code that is faster on all platforms across the board.

Regards,
Jason
