Log Message:
Retire XEN_COMPAT_030001 as detailed on port-xen@:
http://mail-index.netbsd.org/port-xen/2012/06/25/msg007431.html
The xen_p2m API comes next.
ok bouyer@.
Tested on i386 PAE and amd64 (Xen 3.3 on private test bed, and
Xen 3.4 for Amazon EC2).
FWIW, Amazon always reported:
hypervisor0 at mainbus0: Xen version 3.4.3-kaos_t1micro
multiple times for Europe and US West-1, so I guess they are now at
3.4 (32 and 64 bits).
