From 38200cf24702e5d79ce6c8f4c62036c41845c62d Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 21 Oct 2014 12:50:04 -0700 Subject: rcu: Remove "cpu" argument to rcu_note_context_switch() The "cpu" argument to rcu_note_context_switch() is always the current CPU, so drop it. This in turn allows the "cpu" argument to rcu_preempt_note_context_switch() to be removed, which allows the sole use of "cpu" in both functions to be replaced with a this_cpu_ptr(). Again, the anticipated cross-CPU uses of these functions has been replaced by NO_HZ_FULL. Signed-off-by: Paul E.
