        src/sys/arch/xen/xen: xen_machdep.c

Log Message:
Use xcall to suspend/resume clocks on _all_ CPUs, not just current.

Compile-tested only -- kernel still runs but I haven't exercised this
code path.

By code inspection, this change or something like it is obviously
_necessary_ for Xen MP suspend/resume -- otherwise there's no logic
to suspend/resume the clocks on any CPU except the one that actually
triggers sysctl -w machdep.xen.suspend=1.

Whether this change is _sufficient_ for Xen MP suspend/resume to
work, I don't know.

ok cherry
