Pull arm64 fixes from Will Deacon:
 "Inevitably, after saying that I hoped we would be done on the fixes
  front, a couple of issues have cropped up over the last week. Next
  time I'll stay schtum.

  We've fixed an over-eager BUILD_BUG_ON() which Arnd ran into with
  arndconfig, as well as ensuring that KPTI really is disabled on
  Thunder-X1, where the cure is worse than the disease (this regressed
  when we reworked the heterogeneous CPU feature checking).

  Summary:

   - Fix disabling of kpti on Thunder-X machines

   - Fix premature BUILD_BUG_ON() found with randconfig"
