[PATCH tip/core/rcu 0/8] Torture-test updates for 4.5

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

Hello!

This series contains torture-test updates:

1.	Add batch number to script printout to allow easier estimation
	of test duration.

2.	Dump stack when RCU's grace-period kthread stalls.

3.	Set the scripting's default test-hang "grace period" to three
	minutes, and allow this to be overridden.

4.	Remove the obsolete CONFIG_RCU_USER_QS Kconfig option from
	the rcutorture selftest documentation, courtesy of Yang Shi.

5.	Print symbolic name for rcu_torture_writer_state, saving the
	time otherwise required to manually translate from integer
	to symbol.

6.	Print symbolic name for ->gp_state, again saving the time
	otherwise required to manually translate from integer to symbol.

7.	Abbreviate console error dump, allowing the results of an
	rcutorture script run to be observed with less back-scrolling.

8.	Place console.log files correctly from the get-go, preventing
	multiple qemu instances from outputting to the same file.

							Thanx, Paul
