Subject: [PATCH v4 09/45] powerpc/ptdump: Add _PAGE_COHERENT flag
Date: Tue, 19 May 2020 05:48:51 +0000 (UTC)
Message-ID: <324c3d860717e8e91fca3bb6c0f8b23e1644a404.1589866984.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1589866984.git.christophe.leroy@csgroup.eu>

For platforms using shared.c (4xx, Book3e, Book3s/32),
also handle the _PAGE_COHERENT flag with corresponds to the
M bit of the WIMG flags.
