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.
