Merge tag 'x86-splitlock-2021-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 splitlock updates from Ingo Molnar:
- Add the "ratelimit:N" parameter to the split_lock_detect= boot
option, to rate-limit the generation of bus-lock exceptions.
This is both easier on system resources and kinder to offending
applications than the current policy of outright killing them.
- Document the split-lock detection feature and its parameters.
