Hi Thomas and Boris,

This mini series is in response to Thomas's feedback here[1].

I hope this addresses all/most of your concerns you raised in this thread.

Sorry if I missed any, drop more hints and I'll fix them up.

Patch3 needs an AMD change as well. I wasn't confident looking at the
source that was returning the patchid vs reading fromt he real MSR. I'll
check with Boris to confirm before I submit this again.

Now that the other patches are now staged in tip/x86/microcode,
this series applies on top of that.

Cheers,
Ashok
