From 9d36dfcf219e2ba1f1d169a7f92dcf2cbd4e05f0 Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Wed, 19 May 2010 01:19:18 +0400 Subject: [PATCH] perf, x86: P4_pmu_schedule_events -- use smp_processor_id instead of raw_ This snippet somehow escaped the commit: | commit 137351e0feeb9f25d99488ee1afc1c79f5499a9a | Author: Cyrill Gorcunov | Date: Sat May 8 15:25:52 2010 +0400 | | x86, perf: P4 PMU -- protect sensible procedures from preemption so bring it eventually back. It helps to catch preemption issue (if there will be, rule of thumb -- don't use raw_ if you can).
