From 11113334d1c5dd5355c86e531c29f1202a855c86 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 24 Oct 2012 18:05:51 +0200 Subject: vtime: Make vtime_account_system() irqsafe vtime_account_system() currently has only one caller with vtime_account() which is irq safe. Now we are going to call it from other places like kvm where irqs are not always disabled by the time we account the cputime. So let's make it irqsafe. The arch implementation part is now prefixed with "__". vtime_account_idle() arch implementation is prefixed accordingly to stay consistent.
