From 8fa7845df539105a8962c3173c866483da74ff6d Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 22 Oct 2014 15:07:37 -0700 Subject: rcu: Remove "cpu" argument to rcu_cleanup_after_idle() The "cpu" argument to rcu_cleanup_after_idle() is always the current CPU, so drop it. This moves the smp_processor_id() from the caller to rcu_cleanup_after_idle(), saving argument-passing overhead. Again, the anticipated cross-CPU uses of these functions has been replaced by NO_HZ_FULL. Signed-off-by: Paul E.
