Subject: [PATCH tip/core/rcu 0/4] Review comments, cleanups, and
	preemptable synchronize_rcu() fixes

This patchset provides updates to TREE_PREEMPT_RCU as follows:

1.	Update the TREE_PREEMPT_RCU description to note that it is
	suitable for small machines.

2.	Add some WARN_ON_ONCE() calls to check for (incorrect)
	concurrent grace-period initialization.

3.	Simplify quiescent-state detection (which also speeds up
	TREE_PREEMPT_RCU grace periods slightly).

4.	Fix a thinko in TREE_PREEMPT_RCU's synchronize_rcu() that
	could result in premature grace periods.
