unbind xen3 frontend drivers

[Christoph Egger <Christoph_Egger%gmx.de@localhost>]

Hi!


Xen supports ia64 aside of x86. It allows to run
both HVM and PV guests.
HVM guests may also use PV drivers.


In order to make PV drivers available for NetBSD
as HVM guest, I have to unbind the xen3 frontend
drivers from the PV guest only context.

This means, I need to move the following files
into a seperate directory:

if_xennet_xenbus.c
xbd_xenbus.c
xennet_checksum.c

In my working tree, I moved them to
sys/arch/xen/dev

Is this directory ok or
should I move them
to sys/dev/xen/xen and xenbus to sys/dev/xen/xenbus ?
