Subject: [uml-devel] [PATCH 2/5] um: Serve io_remap_pfn_range()
Date: Tue, 7 Feb 2012 01:22:47 +0100 [thread overview]
Message-ID: <1328574170-2286-2-git-send-email-richard@nod.at> (raw)
In-Reply-To: <1328574170-2286-1-git-send-email-richard@nod.at>
At some places io_remap_pfn_range() is needed.
UML has to serve it like all other archs do.
