Subject: [PATCH 4/6] perf pmu: Refactor pmu_add_cpu_aliases()
Date: Thu, 5 Mar 2020 19:08:04 +0800	[thread overview]
Message-ID: <1583406486-154841-5-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1583406486-154841-1-git-send-email-john.garry@huawei.com>

Create pmu_add_cpu_aliases_map() from pmu_add_cpu_aliases(), so the caller
can pass the map; the pmu-events test would use this since there would
be no CPUID matching to a mapfile there.
