#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 merge fix from Ingo Molnar:
#      "I missed one other semantic conflict that can result in build failures
#       on certain stripped down x86 32-bit configs, for example 32-bit
#       'allnoconfig' where CONFIG_X86_IOPL_IOPERM gets turned off"
