#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Ingo Molnar:
#     
#      - Fix an early boot crash in the RSDP parsing code by effectively
#        turning off the parsing call - we ran out of time but want to fix the
#        regression. The more involved fix is being worked on.
#     
#      - Fix a crash that can trigger in the kmemlek code.
#     
#     * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       x86/mm: Fix a crash with kmemleak_scan()
#       x86/boot: Disable RSDP parsing temporarily
