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 in this cycle were:

   - a refactoring of the early virt init code by merging 'struct
     x86_hyper' into 'struct x86_platform' and 'struct x86_init', which
     allows simplifications and also the addition of a new
     ->guest_late_init() callback. (Juergen Gross)

   - timer_setup() conversion of the UV code (Kees Cook)"

* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/virt/xen: Use guest_late_init to detect Xen PVH guest
  x86/virt, x86/platform: Add ->guest_late_init() callback to hypervisor_x86 structure
  x86/virt, x86/acpi: Add test for ACPI_FADT_NO_VGA
  x86/virt: Add enum for hypervisors to replace x86_hyper
  x86/virt, x86/platform: Merge 'struct x86_hyper' into 'struct x86_platform' and 'struct x86_init'
  x86/platform/UV: Convert timers to use timer_setup()
