Here's a patch that enables HYPERVISOR_sched_op() and
HYPERVISOR_sched_opt_compat() for ia64. We currently have no users of
this call, but there's no harm in enabling it (tested by adding a
HYPERVISOR_yield() call to default_idle()). I did notice a problem
with
the compat interface though, nothing defines __XEN_INTERFACE_VERSION__
for the build of xen. We're therefore stuck on interface version
0x00000000 where __HYPERVISOR_sched_op_compat ==
__HYPERVISOR_sched_op.
Well, it doesn't actually matter right now since Xen itself does not
use the __HYPERVISOR_foo numbers. But yes, I can see this might bite
us later so we ought to define it.
Ah, I'm forgetting you have a hypercall switch statement. I'll add the
version number.
With regard to your patch, actually I was thinking more about the vmx
hypercall interface which already supports sched_op_compat --- should
that one have sched_op added too, in vmx_hypercall.c?
