Subject: [PATCH 13/13] mm: allow HMM_MIRROR on all architectures with MMU
Date: Tue, 30 Jul 2019 08:52:03 +0300	[thread overview]
Message-ID: <20190730055203.28467-14-hch@lst.de> (raw)
In-Reply-To: <20190730055203.28467-1-hch-jcswGhMUV9g@public.gmane.org>

There isn't really any architecture specific code in this page table
walk implementation, so drop the dependencies.
