From f7f66b05aa2ac2632c5441a3f129f3be827fe7e7 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Sun, 17 Aug 2014 12:30:34 -0500 Subject: watchdog: Replace __raw_get_cpu_var uses Most of these are the uses of &__raw_get_cpu_var for address calculation. touch_softlockup_watchdog_sync() uses __raw_get_cpu_var to write to per cpu variables. Use __this_cpu_write instead.
