From 440286993960bea4aa09d912a5497d92d09ae54c Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Fri, 21 Jan 2022 20:58:10 -0800 Subject: perf cpumap: Migrate to libperf cpumap api MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Switch from directly accessing the perf_cpu_map to using the appropriate libperf API when possible. Using the API simplifies the job of refactoring use of perf_cpu_map.
