Pull timer updates from Thomas Gleixner:
 "Time, timekeeping and related device driver updates:

  Core:

   - A set of fixes, cleanups and enhancements to the posix timer code:

       - Prevent another possible live lock scenario in the exit() path,
         which affects POSIX_CPU_TIMERS_TASK_WORK enabled architectures.

       - Fix a loop termination issue which was reported syzcaller/KSAN
         in the posix timer ID allocation code.

         That triggered a deeper look into the posix-timer code which
         unearthed more small issues.

       - Add missing READ/WRITE_ONCE() annotations

       - Fix or remove completely outdated comments

       - Document places which are subtle and completely undocumented.

   - Add missing hrtimer modes to the trace event decoder

   - Small cleanups and enhancements all over the place

  Drivers:

   - Rework the Hyper-V clocksource and sched clock setup code

   - Remove a deprecated clocksource driver

   - Small fixes and enhancements all over the place"
