I'm somewhat surprised to see that it also includes a new feature, namely
support for Intel's new RDRAND instruction to get random bits ("Bull
Mountain"):
67c1930 ("x86, random: Verify RDRAND functionality and allow it to be disabled")
5e6321d ("x86, random: Architectural inlines to get random integers with RDRAND")
This was apparently backported from 3.2 via Paul's 2.6.34 tree. Did you
test this release on a CPU with RDRAND? The commits are small, but they
don't really qualify as bugfix-only...
In v3.0-stable the various changes to mix more randomness in the entropy
pool were backported without this feature.
Thanks,
