[PATCH tip/core/rcu 0/14] Tracing changes for 3.8

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

Hello!

This patch series splits RCU's debugfs tracing files into per-RCU-flavor
directories and allows seeking to CPUs.  The patches in this series are
as follows:

1.	Create per-RCU-flavor debugfs directories.  (Courtesy of
	Michael Wang.)
2.	Add functions used by later patches to allow seeking to a given
	CPU.  (Courtesy of Michael Wang.)
3-5.	Convert rcudata, rcudata.csv, and rcu_pending to the new debugfs
	format.  (Courtesy of Michael Wang.)
6.	Replace the old interface with the new one.  (Courtesy of
	Michael Wang.)
7.	Remove the unused rcudata.csv interface.  (Courtesy of Michael Wang.)
8.	Fix formatting of grace-period numbers in rcugp debugfs output.
9-12.	Split rcubarrier, rcuboost, rcugp, and rcuhier by RCU flavor.
	(Courtesy of Michael Wang.)
13.	Remove old debugfs interfaces and stop printing RCU flavor in
	output given that it is implied by the directory name.
	(Courtesy of Michael Wang.)
14.	Add debugfs tracing for synchronize_sched_expedited().

							Thanx, Paul
