# 
#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Thomas Gleixner:
#      "A small set of x86 fixes:
#     
#        - Prevent a NULL pointer dereference in the X2APIC code in case of a
#          CPU hotplug failure.
#     
#        - Prevent boot failures on HP superdome machines by invalidating the
#          level2 kernel pagetable entries outside of the kernel area as
#          invalid so BIOS reserved space won't be touched unintentionally.
#     
#          Also ensure that memory holes are rounded up to the next PMD
#          boundary correctly.
#     
#        - Enable X2APIC support on Hyper-V to prevent boot failures.
#     
#        - Set the paravirt name when running on Hyper-V for consistency
#     
#        - Move a function under the appropriate ifdef guard to prevent build
#          warnings"
#     
#     * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       x86/boot/acpi: Move get_cmdline_acpi_rsdp() under #ifdef guard
#       x86/hyperv: Set pv_info.name to "Hyper-V"
#       x86/apic/x2apic: Fix a NULL pointer deref when handling a dying cpu
#       x86/hyperv: Make vapic support x2apic mode
#       x86/boot/64: Round memory hole size up to next PMD page
#       x86/boot/64: Make level2_kernel_pgt pages invalid outside kernel area
