Subject: [PATCH tip/core/rcu 0/12] Miscellaneous fixes for v5.4
Date: Thu, 1 Aug 2019 15:37:08 -0700	[thread overview]
Message-ID: <20190801223708.GA14862@linux.ibm.com> (raw)

Hello!

This series contains miscellaneous fixes:

1.	Make lockdep's print_lock() address visible.

2.	Fix tick_broadcast_offline() lockdep complaint.

3.	Restore barrier() to rcu_read_lock() and rcu_read_unlock().

4.	Add kernel parameter to dump trace after RCU CPU stall warning.

5.	Add destroy_work_on_stack() to match INIT_WORK_ONSTACK().

6.	Avoid srcutorture security-based pointer obfuscation.

7.	Change return type of rcu_spawn_one_boost_kthread(), courtesy of
	Byungchul Park.

8.	Add rcutree.kthread_prio pointer to stallwarn.txt.

9.	Prevent late-arriving interrupts from disrupting offline, courtesy
	of Peter Zijlstra.

10.	Remove redundant "if" condition from rcu_gp_is_expedited().

11.	Use common outgoing-CPU-notification code for arm.

12.	Fix spelling mistake "greate"->"great", courtesy of Mukesh Ojha.

							Thanx, Paul
