From: Maxim Levitsky Date: Mon, 18 Jul 2022 14:11:19 +0000 (+0300) Subject: perf/x86/intel/lbr: Use setup_clear_cpu_cap() instead of clear_cpu_cap() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b329f5ddc9ce4b622d9c7aaf5c6df4de52caf91a;p=linux.git perf/x86/intel/lbr: Use setup_clear_cpu_cap() instead of clear_cpu_cap() clear_cpu_cap(&boot_cpu_data) is very similar to setup_clear_cpu_cap() except that the latter also sets a bit in 'cpu_caps_cleared' which later clears the same cap in secondary cpus, which is likely what is meant here.
