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

Pull x86 updates from Thomas Gleixner:
 "A pile of regression fixes and updates:

   - address the fallout of the patches which made the cpuid - nodeid
     relation permanent: Handling of invalid APIC ids and preventing
     pointless warning messages.

   - force eager FPU when protection keys are enabled. Protection keys
     are not generating FPU exceptions so they cannot work with the lazy
     FPU mechanism.

   - prevent force migration of interrupts which are not part of the CPU
     vector domain.

   - handle the fact that APIC ids are not updated in the ACPI/MADT
     tables on physical CPU hotplug

   - remove bash-isms from syscall table generator script

   - use the hypervisor supplied APIC frequency when running on VMware"
