rcu: Add online/offline info to stall warning message
This commit makes the RCU CPU stall warning message print online/offline indications immediately after a hyphen following the CPU number. A "O" indicates that the global CPU-hotplug system believes that the CPU is online, a "o" that RCU perceived the CPU to be online at the beginning of the current expedited grace period, and an "N" that RCU currently believes that it will perceive the CPU as being online at the beginning of the next expedited grace period, with "." otherwise for all three indications. So for CPU 10, you would normally see "10-OoN:" indicating that everything believes that the CPU is online. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
