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" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/pkeys: Make protection keys an "eager" feature x86/apic: Prevent pointless warning messages x86/acpi: Prevent LAPIC id 0xff from being accounted arch/x86: Handle non enumerated CPU after physical hotplug x86/unwind: Fix oprofile module link error x86/vmware: Skip lapic calibration on VMware x86/syscalls: Remove bash-isms in syscall table generator x86/irq: Prevent force migration of irqs which are not in the vector domain
