Linus Torvalds 25144ea31b - 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

 - 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
