#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Thomas Gleixner:
#      "The accumulated fixes from this and last week:
#     
#        - Fix vmalloc TLB flush and map range calculations which lead to
#          stale TLBs, spurious faults and other hard to diagnose issues.
#     
#        - Use fault_in_pages_writable() for prefaulting the user stack in the
#          FPU code as it's less fragile than the current solution
#     
#        - Use the PF_KTHREAD flag when checking for a kernel thread instead
#          of current->mm as the latter can give the wrong answer due to
#          use_mm()
#     
#        - Compute the vmemmap size correctly for KASLR and 5-Level paging.
#          Otherwise this can end up with a way too small vmemmap area.
#     
#        - Make KASAN and 5-level paging work again by making sure that all
#          invalid bits are masked out when computing the P4D offset. This
#          worked before but got broken recently when the LDT remap area was
#          moved.
#     
#        - Prevent a NULL pointer dereference in the resource control code
#          which can be triggered with certain mount options when the
#          requested resource is not available.
#     
#        - Enforce ordering of microcode loading vs. perf initialization on
#          secondary CPUs. Otherwise perf tries to access a non-existing MSR
#          as the boot CPU marked it as available.
#     
#        - Don't stop the resource control group walk early otherwise the
#          control bitmaps are not updated correctly and become inconsistent.
#     
#        - Unbreak kgdb by returning 0 on success from
#          kgdb_arch_set_breakpoint() instead of an error code.
#     
#        - Add more Icelake CPU model defines so depending changes can be
#          queued in other trees"
#
