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
