Subject: [PATCH v2 13/20] powerpc: perf/core: advertise PMU exclusion capability
Date:   Mon, 26 Nov 2018 11:12:29 +0000
Message-Id: <1543230756-15319-14-git-send-email-andrew.murray@arm.com>
In-Reply-To: <1543230756-15319-1-git-send-email-andrew.murray@arm.com>
References: <1543230756-15319-1-git-send-email-andrew.murray@arm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

For PowerPC PMUs that have the capability to exclude events
based on context. Let's advertise that we support the
PERF_PMU_CAP_EXCLUDE capability to ensure that perf doesn't
prevent us from handling events where any exclusion flags are
set.
