Subject: [PATCH tip/core/rcu 0/11] Fixes for 3.13

Hello!

This series provides the following miscellaneous fixes:

1.	Place a preemption point in do_mlockall().

2.	Use proper cpp macro for ->gp_flags instead of the constant "1".

3.	Convert a number of local functions to static.

4.	Fix a dubious "if" condition to use "||" rather than "|"
	(we were getting lucky...).

5.	Make list_splice_init_rcu() account for RCU readers.

6.	Replace __get_cpu_var() uses, courtesy of Christoph Lameter.

7.	Silence an unused-variables warning in rcu_eqs_enter_common()
	and rcu_eqs_exit_common().

8.	Micro-optimize rcu_cpu_has_callbacks().

9.	Reject memory-order-induced stall-warning false positives.

10.	Apply tracepoint_string() to rcutiny's trace events.

11.	Avoid a CONFIG_RCU_NOCB_CPU_ALL=y panic on systems with sparse
	CPU numbering, courtesy of Kirill Tkhai.

							Thanx, Paul
