Merge branch 'clocksource' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into timers/core
Pull clocksource watchdog updates from Paul McKenney:
- Avoid accidental unstable marking of clocksources by rejecting
clocksource measurements where the source of the skew is the delay
reading reference clocksource itself. This change avoids many of the
current false positives caused by epic cache-thrashing workloads.
- Reduce the default clocksource_watchdog() retries to 2, thus offsetting
the increased overhead due to #1 above rereading the reference
clocksource.
