From 24f1a79a5fc10858e05ee0bf651ec99abfc0319b Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Tue, 13 Oct 2015 09:09:10 +0200 Subject: [PATCH] perf/powerpc: Add support for PERF_SAMPLE_BRANCH_CALL The patch catches PERF_SAMPLE_BRANCH_CALL because it is not clear whether this is actually supported by the hardware.
