perf, x86: P4_pmu_schedule_events -- use smp_processor_id instead of raw_
This snippet somehow escaped the commit: | commit 137351e0feeb9f25d99488ee1afc1c79f5499a9a | Author: Cyrill Gorcunov <gorcunov@openvz.org> | 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).
