Subject: Re: [PATCH v6 3/5] random: use SipHash in place of MD5

Hi Andy, Ted,

I've made the requested changes. Keys now rotate and are per-CPU
based. The chaining value is now additive instead of replacing.

DavidL suggested I lower the velocity of `git-send-email` triggers, so
if you'd like to take a look at this before I post v7, you can follow
along at my git tree here:

Choose the commit entitled "random: use SipHash in place of MD5"

Thanks,
Jason
