I did a clean build of the world after a cvs update of the source tree
and the problem mentioned in this PR is still present:

# dtrace -n 'sdt:xen:clock:, sdt:xen:hardclock:, sdt:xen:timecounter: { printf("%d %d %d %d %d %d %d %d", arg0, arg1, arg2, arg3, arg4, arg5, arg6, arg7) }'
dtrace: invalid probe specifier sdt:xen:clock:, sdt:xen:hardclock:, sdt:xen:timecounter: { printf("%d %d %d %d %d %d %d %d", arg0, arg1, arg2, arg3, arg4, arg5, arg6, arg7) }: "/usr/lib/dtrace/psinfo.d", line 46: syntax error near "u_int"



I noted that a difference between GENERIC and XEN3_DOM0 is that there is
a 'makeoptions DEBUG="-g"' present with a comment that it is needed for
CTF and this option isn't present in XEN3_DOMU.  This is probably
another problem, but if you try to build a XEN3_DOMU kernel with
DEBUG="-g" you get this during link:

I am pretty sure that the cvs updated correctly:
