Update of /cvs/pkgs/rpms/kernel-xen-2.6/devel
In directory cvs-int.fedora.redhat.com:/tmp/cvs-serv18187

Modified Files:
	kernel.spec 
Added Files:

Log Message:
x86_64: Reserve kernel text and data segments at boot (bug #438000)

As the main x86_64 xen patch is generated from the rebase on markmc's
tree, added the fix as a separated patch to make it easier to see which
patches are on markmc's git tree and which patches aren't.
