Subject: [PATCH v2 10/13] perf tools: add branch-brs as a new event
From:   Stephane Eranian <eranian@google.com>
To:     linux-kernel@vger.kernel.org
Cc:     peterz@infradead.org, kim.phillips@amd.com, acme@redhat.com,
        jolsa@redhat.com, songliubraving@fb.com, mpe@ellerman.id.au,
        maddy@linux.ibm.com

Precedence: bulk

Although branch-brs is specific to AMD Zen3, we provide it in the list of
events recognized by perf as a convenience. It allows: $ perf stat -e
branch-brs $ perf list

and enable some test suite to pass.
