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
