Linus Torvalds cd336f6562 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      - Fix or remove completely outdated comments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
