* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, kvm: KVM paravirt kernels don't check for CPUID being unavailable
  x86: Fix section annotation of acpi_map_cpu2node()
  x86/microcode: Ensure that module is only loaded on supported Intel CPUs

* 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
