#     Merge tag 'x86-entry-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 entry code updates from Thomas Gleixner:
#      "More consolidation and correctness fixes for the debug exception:
#     
#        - Ensure BTF synchronization under all circumstances
#     
#        - Distangle kernel and user mode #DB further
#     
#        - Get ordering vs. the debug notifier correct to make KGDB work more
#          reliably.
#     
#        - Cleanup historical gunk and make the code simpler to understand"
