Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu updates from Ingo Molnar:
"The main changes in this cycle were:
- Improved CPU ID handling code and related enhancements (Borislav
Petkov)
- RDRAND fix (Len Brown)"
* 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86: Replace RDRAND forced-reseed with simple sanity check
x86/MSR: Chop off lower 32-bit value
x86/cpu: Fix MSR value truncation issue
x86/cpu/amd, kvm: Satisfy guest kernel reads of IC_CFG MSR
kvm: Add accessors for guest CPU's family, model, stepping
x86/cpu: Unify CPU family, model, stepping calculation
