[GIT PULL] random subsystem for 3.6
From: Theodore Ts'o
Date: Tue Jul 31 2012 - 12:45:31 EST
Sorry for the delay, but Peter felt very strongly about the last
patch, and I wanted to give it at least a day's baking time in
linux-next before I submitted a pull request to you.
Also note that that are some minor merge conflicts. See my proposed resolution here:

random: mix in architectural randomness in extract_buf() (2012-07-27 22:37:20 -0400)
----------------------------------------------------------------
This patch series contains a major revamp of how we collect entropy
from interrupts for /dev/random and /dev/urandom. The goal is to
addresses weaknesses discussed in the paper "Mining your Ps and Qs:
Detection of Widespread Weak Keys in Network Devices", by Nadia
Heninger, Zakir Durumeric, Eric Wustrow, J. Alex Halderman, which will
be published in the Proceedings of the 21st Usenix Security Symposium,
August 2012. (See https://factorable.net for more information and an
extended version of the paper.)
