[PATCH 00/20] rcu/context-tracking: Merge RCU eqs-dynticks counter to context tracking v5

This is the same as rcu:ctxt.2022.06.21a (no rebase) with minimal changes
on the following patches:

* [06/20] fix missing function renames on xtensa (thanks Max Filippov, SOB added)
* [09/20] fix missing Kconfig renames on xtensa (thanks Max Filippov, SOB added)
and also on loongarch.
* [18/20] remove unecessary and buggy notrace from rcu_preempt_deferred_qs(). It's called
after intrumentation_begin() in EQS functions.

HEAD: cb0045adde39bba5ffc620a184b1685a869569d8

Thanks,
