#     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 set of fixes for x86:
#     
#        - Prevent multiplication result truncation on 32bit. Introduced with
#          the early timestamp reworrk.
#     
#        - Ensure microcode revision storage to be consistent under all
#          circumstances
#     
#        - Prevent write tearing of PTEs
#     
#        - Prevent confusion of user and kernel reegisters when dumping fatal
#          signals verbosely
#     
#        - Make an error return value in a failure path of the vector
#          allocation negative. Returning EINVAL might the caller assume
#          success and causes further wreckage.
#     
#        - A trivial kernel doc warning fix"
#     
#     * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       x86/mm: Use WRITE_ONCE() when setting PTEs
#       x86/apic/vector: Make error return value negative
#       x86/process: Don't mix user/kernel regs in 64bit __show_regs()
#       x86/tsc: Prevent result truncation on 32bit
#       x86: Fix kernel-doc atomic.h warnings
#       x86/microcode: Update the new microcode revision unconditionally
#       x86/microcode: Make sure boot_cpu_data.microcode is up-to-date
