Subject: [PATCH 5/7] m68knommu: add a pgprot_noncached stub
Date: Mon, 5 Aug 2019 12:11:57 +0300 [thread overview]
Message-ID: <20190805091159.7826-6-hch@lst.de> (raw)
In-Reply-To: <20190805091159.7826-1-hch@lst.de>
Provide a pgprot_noncached like all the other nommu ports so that
common code can rely on it being able to be present. Note that this is
generally code that is not actually run on nommu, but at least we can
avoid nasty ifdefs by having a stub.
