there is a missing
#include "opt_xen.h" in i386/cpufunc.S
without it the kenrel doesn't build

A XEN3_DOM0 kernel fails with:
Loaded initial symtab at 0xc09875e0, strtab at 0xc09ea82c, # entries 23879
panic: kernel diagnostic assertion "doing_shutdown || curlwp != NULL || 
(map->flags & VM_MAP_INTRSAFE)" failed: file 
"/dsk/l1/misc/bouyer/current/src/sys/uvm/uvm_map.c", line 1078
Stopped at      netbsd:breakpoint+0x1:  ret

This is before the copyright string is printed; I never get the db> prompt
(maybe it's too early at this point to have a full ddb working).

A XEN3_DOMU kernel doesn't start, it seems to be looping before console
is working.

A XEN2_DOM0 fails in the same way a XEN3_DOM0 kernel.
