Subject: [PATCH tip/core/rcu 0/8] RCU list-traversal lockdep updates for v5.4

Hello!

This series provides enhancements to RCU pointer and list macros, all
courtesy of Joel Fernandes:

1.	Rename rcu_dereference_raw_notrace() to _check().

2.	Remove redundant debug_locks check in rcu_read_lock_sched_held().

3.	Add support for consolidated-RCU reader checking.

4.	Remove custom check for RCU readers.

5.	Add lockdep condition to fix for_each_entry().

6.	Convert to use built-in RCU list checking.

7.	Pass lockdep condition to pcm_mmcfg_list iterator.

8.	Use built-in RCU list checking for acpi_ioremaps list.

							Thanx, Paul
