This patch claims one reserved grant entry for the console and another for the xenstore. It modifies the builder to fill in the grant table entries for the console and the xenstore. Previous versions of this patch have been sent to xen-devel. See http://lists.xensource.com/archives/html/xen-devel/2008-07/msg00610.html http://lists.xensource.com/archives/html/xen-devel/2009-03/msg01491.html Signed-off-by: Diego Ongaro <diego.ongaro@citrix.com> Signed-off-by: Alex Zeffertt <alex.zeffertt@eu.citrix.com> Signed-off-by: Daniel De Graaf <dgdegra@tycho.nsa.gov> Acked-by: Ian Campbell <ian.campbell@citrix.com> Cc: Ian Jackson <ian.jackson@eu.citrix.com> Cc: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Committed-by: Ian Jackson <Ian.Jackson@eu.citrix.com>
