Merge tag 'timers-core-2025-05-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer core updates from Thomas Gleixner:
 "Updates for the time/timer core code:

   - Rework the initialization of the posix-timer kmem_cache and move
     the cache pointer into the timer_data structure to prevent false
     sharing

   - Switch the alarmtimer code to lock guards

   - Improve the CPU selection criteria in the per CPU validation of the
     clocksource watchdog to avoid arbitrary selections (or omissions)
     on systems with a small number of CPUs

   - The usual cleanups and improvements"
