Subject: [PATCH 4/5] powerpc: Replace _ALIGN() by ALIGN()
To:     Benjamin Herrenschmidt <benh@kernel.crashing.org>,

Date:   Mon, 20 Apr 2020 18:36:37 +0000 (UTC)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

_ALIGN() is specific to powerpc
ALIGN() is generic and does the same

Replace _ALIGN() by ALIGN()
