[PATCH v2 0/4] RDSEED support for the Linux kernel

2014-03-17 Thread H. Peter Anvin
Upcoming Intel silicon adds a new RDSEED instruction. Whereas RDRAND returns output from a PRNG, the RDSEED instruction returns fully conditioned entropy that is suitable for use as seeds to a PRNG. This patchset adds support for RDSEED in the Linux kernel in three places: 1. During bootup, use
