From 54d35f29f49224d86b994acb6e5969b9ba09022d Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Mon, 29 Jun 2009 14:44:57 +0900 Subject: sched: Hide runqueues from direct reference at source code level for __raw_get_cpu_var() Hide __raw_get_cpu_var() as well - thus all the direct references to runqueues will abstracted out.
