Subject: [PATCH v2 5/9] m68k/mm: use __ClearPageReserved()
Date: Mon, 14 Jan 2019 13:58:59 +0100 [thread overview]
Message-ID: <20190114125903.24845-6-david@redhat.com> (raw)
In-Reply-To: <20190114125903.24845-1-david@redhat.com>
The PG_reserved flag is cleared from memory that is part of the kernel
image (and therefore marked as PG_reserved). Avoid using PG_reserved
directly.
