From 719254faa17ffedc87ba0fadb9b34e535c9758d5 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 17 Oct 2008 09:59:47 +0200 Subject: NOHZ: unify the nohz function calls in irq_enter() We have two separate nohz function calls in irq_enter() for no good reason. Just call a single NOHZ function from irq_enter() and call the bits in the tick code.
