Merge branch 'x86-hyperv-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86/hyperv changes from Ingo Molnar: "The biggest change is support for Windows 8's improved hypervisor interrupt model on the Linux Hyper-V guest subsystem code side. Smallish fixes otherwise." * 'x86-hyperv-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, hyperv: HYPERV depends on X86_LOCAL_APIC X86: Handle Hyper-V vmbus interrupts as special hypervisor interrupts X86: Add a check to catch Xen emulation of Hyper-V x86: Hyper-V: register clocksource only if its advertised
