Subject: [PATCH 13/15] mm: allow HMM_MIRROR on all architectures with MMU
Date: Tue, 6 Aug 2019 19:05:51 +0300 [thread overview]
Message-ID: <20190806160554.14046-14-hch@lst.de> (raw)
In-Reply-To: <20190806160554.14046-1-hch@lst.de>
There isn't really any architecture specific code in this page table
walk implementation, so drop the dependencies.
