Merge tag 'timers_urgent_for_v6.13_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fix from Borislav Petkov:
- Handle the case where clocksources with small counter width can,
in conjunction with overly long idle sleeps, falsely trigger the
negative motion detection of clocksources
* tag 'timers_urgent_for_v6.13_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
clocksource: Make negative motion detection more robust
