#     Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86/pti updates from Thomas Gleixner:
#      "A mixed bag of fixes and updates for the ghosts which are hunting us.
#     
#       The scheduler fixes have been pulled into that branch to avoid
#       conflicts.
#     
#        - A set of fixes to address a khread_parkme() race which caused lost
#          wakeups and loss of state.
#     
#        - A deadlock fix for stop_machine() solved by moving the wakeups
#          outside of the stopper_lock held region.
#     
#        - A set of Spectre V1 array access restrictions. The possible
#          problematic spots were discuvered by Dan Carpenters new checks in
#          smatch.
#     
#        - Removal of an unused file which was forgotten when the rest of that
#          functionality was removed"
