Subject: [GIT PULL] x86/splitlock changes for v5.14

Linus,

Please pull the latest x86/splitlock git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-splitlock-2021-06-28

   # HEAD: d28397eaf4c27947a1ffc720d42e8b3a33ae1e2a Documentation/x86: Add ratelimit in buslock.rst

Changes in this cycle were:

 - 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.

 Thanks,

	Ingo
