From: "Luis R. Rodriguez" <mcg...@suse.com> Fold Xen front end drivers under their own Kconfig entry. You may want to for example only enable domU guests with pv-drivers.
While at it make HVC_XEN_FRONTEND select HVC_XEN. This is a per the agreed upon Kconfig changes for Xen [0]. [0] http://comments.gmane.org/gmane.comp.emulators.xen.devel/231579 Signed-off-by: Luis R.
