x86/mm: Print likely CPU at segfault time (2022-08-24 12:48:05 +0200)
----------------------------------------------------------------
- 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
----------------------------------------------------------------
