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"
