[PATCH 09/10] drivers/perf: perf/core: generalise event exclusion checking with perf macro
From: Andrew Murray
Date: Fri Nov 16 2018 - 05:24:57 EST
Replace checking of perf event exclusion flags with perf macro.
This is a functional change as exclude_host and exclude_guest are added
in the following files:
- drivers/perf/qcom_l2_pmu.c
- drivers/perf/qcom_l3_pmu.c
- drivers/perf/arm_pmu.c
And exclude_idle and exclude_hv are added in these files:
- drivers/perf/xgene_pmu.c
