Subject: [RFC PATCH v3 8/8] arch: powerpc: adjust fadump alignment to be pageblock aligned.
Date: Wed, 5 Jan 2022 16:47:56 -0500 [thread overview]
Message-ID: <20220105214756.91065-9-zi.yan@sent.com> (raw)
In-Reply-To: <20220105214756.91065-1-zi.yan@sent.com>
From: Zi Yan <ziy@nvidia.com>
CMA only requires pageblock alignment now. Change CMA alignment in
fadump too.
