From 23f66e2d661b4d3226d16e25910a9e9472ce2410 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 27 Aug 2014 11:18:29 -0400 Subject: [PATCH] Revert "powerpc: Replace __get_cpu_var uses" This reverts commit 5828f666c069af74e00db21559f1535103c9f79a due to build failure after merging with pending powerpc changes.
