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

Pull x86 platform updates from Ingo Molnar:
 "The main changes include various Hyper-V optimizations such as faster
  hypercalls and faster/better TLB flushes - and there's also some
  Intel-MID cleanups"

* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  tracing/hyper-v: Trace hyperv_mmu_flush_tlb_others()
  x86/hyper-v: Support extended CPU ranges for TLB flush hypercalls
  x86/platform/intel-mid: Make several arrays static, to make code smaller
  MAINTAINERS: Add missed file for Hyper-V
  x86/hyper-v: Use hypercall for remote TLB flush
  hyper-v: Globalize vp_index
  x86/hyper-v: Implement rep hypercalls
  hyper-v: Use fast hypercall for HVCALL_SIGNAL_EVENT
  x86/hyper-v: Introduce fast hypercall implementation
  x86/hyper-v: Make hv_do_hypercall() inline
  x86/hyper-v: Include hyperv/ only when CONFIG_HYPERV is set
  x86/platform/intel-mid: Make 'bt_sfi_data' const
  x86/platform/intel-mid: Make IRQ allocation a bit more flexible
  x86/platform/intel-mid: Group timers callbacks together
