This series is targetting x86, which typically has RDRAND/RDSEED instructions. Are you referring to other arches? Older x86? Also, isn't this the same requirement for base address KASLR? Don't get me wrong, I want more diverse entropy sources available earlier in the boot process as well. :-) I'm just wondering what's different about this series vs base address KASLR wrt early entropy sources. thx, Jason.
