Merge tag 'timers_urgent_for_v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fixes from Borislav Petkov:
- Reset hrtimers correctly when a CPU hotplug state traversal happens
"half-ways" and leaves hrtimers not (re-)initialized properly
- Annotate accesses to a timer group's ignore flag to prevent KCSAN
from raising data_race warnings
- Make sure timer group initialization is visible to timer tree walkers
and avoid a hypothetical race
- Fix another race between CPU hotplug and idle entry/exit where timers
on a fully idle system are getting ignored
- Fix a case where an ignored signal is still being handled which it
shouldn't be
