Subject: [RFC PATCH 3/3] arch: powerpc: adjust fadump alignment to be pageblock aligned.
Date: Mon, 15 Nov 2021 14:37:24 -0500 [thread overview]
Message-ID: <20211115193725.737539-4-zi.yan@sent.com> (raw)
In-Reply-To: <20211115193725.737539-1-zi.yan@sent.com>
From: Zi Yan <ziy@nvidia.com>
CMA only requires pageblock alignment now. Change CMA alignment in
fadump too.
