Subject: [PATCH 2/2] um: Serve io_remap_pfn_range()
Date: Wed, 25 Jan 2012 18:23:54 +0100 [thread overview]
Message-ID: <1327512234-22578-2-git-send-email-richard@nod.at> (raw)
In-Reply-To: <1327512234-22578-1-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.
