Subject[PATCH tip/core/rcu 08/13] rcu: Remove the CONFIG_TINY_RCU ifdefs in rcutiny.h
Date
From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

Now that CONFIG_TINY_PREEMPT_RCU is no more, this commit removes
the CONFIG_TINY_RCU ifdefs from include/linux/rcutiny.h in favor of
unconditionally compiling the CONFIG_TINY_RCU legs of those ifdefs.

Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
[ paulmck: Moved removal of #else to "Remove TINY_PREEMPT_RCU" as
suggested by Josh Triplett. ]
