Subject: [PATCH] arm64: perf: remove duplicated and unsupported events for Cortex-A73
Date:   Tue, 14 Nov 2017 20:27:59 +0800
Message-ID: <1510662479-9550-1-git-send-email-xuyiping@hisilicon.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

bus access read/write events are not supported in A73, and the definition
is duplicated, so delete it.
