Pull x86 cpu handling changes from Ingo Molnar:
"Bigger changes:
- Intel CPU hardware-enablement: new vector instructions support
(AVX-512), by Fenghua Yu.
- Support the clflushopt instruction and use it in appropriate
places. clflushopt is similar to clflush but with more relaxed
ordering, by Ross Zwisler.
- MSR accessor cleanups, by Borislav Petkov.
- 'forcepae' boot flag for those who have way too much time to spend
on way too old Pentium-M systems and want to live way too
dangerously, by Chris Bainbridge"
