From e465de1cd5e1759e40f077bac287de60d56ad06c Mon Sep 17 00:00:00 2001 From: Alexander Shishkin Date: Wed, 6 Apr 2016 17:35:07 +0300 Subject: perf/x86/intel/pt: Use boot_cpu_has() because it's there At the moment, initialization path is using test_cpu_cap(&boot_cpu_data), to detect PT, which is just open coding boot_cpu_has(). Use the latter instead.
