#     Pull x86 fixes from Thomas Gleixner:
#      "A set of fixes for X86:
#     
#        - Prevent sending the wrong signal when protection keys are enabled
#          and the kernel handles a fault in the vsyscall emulation.
#     
#        - Invoke early_reserve_memory() before invoking e820_memory_setup()
#          which is required to make the Xen dom0 e820 hooks work correctly.
#     
#        - Use the correct data type for the SETZ operand in the EMQCMDS
#          instruction wrapper.
#     
#        - Prevent undefined behaviour to the potential unaligned accesss in
#          the instruction decoder library"
