Linus Torvalds 90450a0616 RCU fixes for v6.7 
* Fix a lock inversion between scheduler and RCU introduced
   in v6.2-rc4. The scenario could trigger on any user of RCU_NOCB
   (mostly Android and also nohz_full).
 
 * Fix PF_IDLE semantic changes introduced in v6.6-rc3 breaking some
   RCU-Tasks and RCU-Tasks-Trace expectations as to what exactly is
   an idle task. This resulted in potential spurious stalls and
   warnings.

Pull RCU fixes from Frederic Weisbecker:

 - Fix a lock inversion between scheduler and RCU introduced in
   v6.2-rc4. The scenario could trigger on any user of RCU_NOCB
   (mostly Android but also nohz_full)

 - Fix PF_IDLE semantic changes introduced in v6.6-rc3 breaking
   some RCU-Tasks and RCU-Tasks-Trace expectations as to what
   exactly is an idle task. This resulted in potential spurious
   stalls and warnings.
