[PATCH tip/core/rcu 7/8] rcu: Inline trivial wrapper function rcu_start_gp_per_cpu()

From: Paul E. McKenney
Date: Fri Apr 12 2013 - 19:33:49 EST


From: "Paul E. McKenney" <paulmck@xxxxxxxxxxxxxxxxxx>

Given the changes that introduce note_gp_change(), rcu_start_gp_per_cpu()
is now a trivial wrapper function with only one caller. This commit
therefore inlines it into its sole call site.
