Subject: [PATCH WIP 4/5] xen: allow privcmd for hvm guests
Date: Wed, 4 Jul 2012 12:15:19 +0100 [thread overview]
Message-ID: <1341400520-31770-4-git-send-email-stefano.stabellini@eu.citrix.com> (raw)
In-Reply-To: <alpine.DEB.2.02.1207041207050.13581@kaball.uk.xensource.com>
Ian's initial XENMAPSPACE_gmfn_foreign implementation is enough to get
privcmd mmap to work for XENFEAT_auto_translated_physmap guests.
