Linus Torvalds 7db99f01d1 - Print the CPU number at segfault time. The number printed is not 
always accurate (preemption is enabled at that time) but the print string
   contains "likely" and after a lot of back'n'forth on this, this was the
   consensus that was reached. See thread starting at:
   https://lore.kernel.org/r/5d62c1d0-7425-d5bb-ecb5-1dc3b4d7d245@intel.com
 
 - After a *lot* of testing and polishing, finally the clear_user()
   improvements to inline REP; STOSB by default

Merge tag 'x86_cpu_for_v6.1_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 cpu updates from Borislav Petkov:

 - Print the CPU number at segfault time.

   The number printed is not always accurate (preemption is enabled at
   that time) but the print string contains "likely" and after a lot of
   back'n'forth on this, this was the consensus that was reached. See
   thread at [1].

 - After a *lot* of testing and polishing, finally the clear_user()
   improvements to inline REP; STOSB by default
