Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 fixes from Ingo Molnar:
 "Misc fixes:

   - A rather involved set of memory hardware encryption fixes to
     support the early loading of microcode files via the initrd. These
     are larger than what we normally take at such a late -rc stage, but
     there are two mitigating factors: 1) much of the changes are
     limited to the SME code itself 2) being able to early load
     microcode has increased importance in the post-Meltdown/Spectre
     era.

   - An IRQ vector allocator fix

   - An Intel RDT driver use-after-free fix

   - An APIC driver bug fix/revert to make certain older systems boot
     again

   - A pkeys ABI fix

   - TSC calibration fixes

   - A kdump fix"
