Log Message:
Pull up revision 1.7 (requested by tls in ticket #1043).

HYPERVISOR_yield is one of the hypervisor calls that's "overloaded"; it
does different things depending what's in %ebx.

We weren't setting %ebx here *at all*; so we did not get SCHEDOP_yield,
which was what was wanted; so unpredictable things happened, notably
immediate return to the NetBSD idle loop, in other words spinning on CPU.
Definitely not cool!

Michael Kukat caught this one and suggested this fix on port-xen.
