#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fix from Thomas Gleixner:
#      "A single fix, which addresses boot failures on machines which do not
#       report EBDA correctly, which can place the trampoline into reserved
#       memory regions. Validating against E820 prevents that"
#     
#     * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       x86/boot/compressed/64: Validate trampoline placement against E820
