#     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 x86 fixes and functional updates:
#     
#        - Prevent stale huge I/O TLB mappings on 32bit. A long standing bug
#          which got exposed by KPTI support for 32bit
#     
#        - Prevent bogus access_ok() warnings in arch_stack_walk_user()
#     
#        - Add display quirks for Lenovo devices which have height and width
#          swapped
#     
#        - Add the missing CR2 fixup for 32 bit async pagefaults. Fallout of
#          the CR2 bug fix series.
#     
#        - Unbreak handling of force enabled HPET by moving the 'is HPET
#          counting' check back to the original place.
#     
#        - A more accurate check for running on a hypervisor platform in the
#          MDS mitigation code. Not perfect, but more accurate than the
#          previous one.
#     
#        - Update a stale and confusing comment vs. IRQ stacks"
#
