  hrtimers: Handle CPU state correctly on hotplug (2025-01-16 13:06:14 +0100)

----------------------------------------------------------------
- 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
