Hello!

The following miscellaneous fixes come before the infamous ->gp_seq
conversion:

1.	Add debugging info to the assertion detecting tasks queued on
	the ->blkd_tasks list at unexpected times.

2.	Use the proper lockdep annotation in dump_blkd_tasks(), courtesy
	of Boqun Feng.

3.	Exclude near-simultaneous RCU CPU stall warnings, thus reducing
	the probability of interleaved (and thus inscrutable) warnings.

4.	Add diagnostics for failure to respond to a request for a new
	grace period.

5.	Make rcu_gp_cleanup() write only once to ->gp_flags.

							Thanx, Paul
