Subject: [GIT PULL clocksource] Clocksource watchdog commits for v5.18

Hello, Thomas,

This pull request contains a single change that allows build-time
adjustment of the clocksource watchdog maximum skew.  The default remains
100 microseconds, but a new CLOCKSOURCE_WATCHDOG_MAX_SKEW_US Kconfig
option allows kernels to be built with this skew set in a range from
50 to 100 microseconds.  This Kconfig option depends on the existing
CLOCKSOURCE_WATCHDOG option.  This change has been posted to LKML:

https://lore.kernel.org/lkml/20211206033815.871823-1-longman@redhat.com/

this has been subjected to the kbuild test robot and -next testing,
and are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git clocksource.2022.02.01b

  clocksource: Add a Kconfig option for WATCHDOG_MAX_SKEW (2022-02-01 17:35:43 -0800)

Please note that this is based on this mainline commit:

da123016ca8c ("rcu-tasks: Fix computation of CPU-to-list shift counts")

which is in turn based on v5.17-rc1.
