Re: merge bouyer-xenpvh to HEAD

Compilation with CFLAGS+=XEN fails with:
In file included from ./machine/intr.h:3,
                 from /home/sysbuild/src/sys/sys/intr.h:97,
                 from /home/sysbuild/src/sys/sys/mutex.h:174,
                 from ./machine/vmparam.h:42,
                 from /home/sysbuild/src/sys/uvm/uvm_param.h:76,
                 from /home/sysbuild/src/sys/sys/param.h:149,
                 from /tmp/genassym.cYoGAh/assym.c:13:
./x86/intr.h:52:10: fatal error: xen/include/public/xen.h: No such
file or directory
 #include <xen/include/public/xen.h>
so probably there is more to it than this.
