Subject: [GIT PULL] x86/splitlock for 6.2

Hi Linus,

Please pull some x86/splitlock changes for v6.2.

This includes a single change which enables users to reduce the
penalty inflicted on split lock users.  There are some
proprietary, binary-only games which because entirely unplayable
with the old penalty.

Anyone opting into the new mode is, of course, more exposed to
the DoS nasitness inherent with split locks, but they can play
their games again.


The following changes since commit f0c4d9fc9cc9462659728d168387191387e903cc:

  Linux 6.1-rc4 (2022-11-06 15:07:11 -0800)
