From 92519bbc8af612975410def52bd462ca9af85cdb Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Fri, 20 Sep 2013 13:08:50 +0200 Subject: [PATCH] perf/x86/intel: Fix build warning in intel_pmu_drain_pebs_nhm() Fengguang Wu reported this build warning: arch/x86/kernel/cpu/perf_event_intel_ds.c: In function 'intel_pmu_drain_pebs_nhm': arch/x86/kernel/cpu/perf_event_intel_ds.c:964:2: warning: format '%ld' expects argument of type 'long int', but argument 4 has type 'int' Because pointer arithmetics result type is bitness dependent there's no natural type to use here, cast it to long.
