Richard,
xen interface in mkfile is 30201.
Are you sure you wanted it to be 30201? Not 30202? I had a problem due
to the setting -- a compat function was being called instead of the
right one.
Or is it really 30303 at this point?
There is one remaining problem with the cppx or cpp. When this is run,
and physdev.h is included, you get two lines like this:
#define PHYSDEVOP_IRQ_NEEDS_UNMASK_NOTIFY(1U<<(0))
#define PHYSDEVOP_IRQ_SHARED(1U<<(1))
note lack of space after the name. Not sure why, but you might find it
faster than I will.

I believe it has to be < 30202, because we still use the old form of
event_channel_op hypercall. We could update xensystem.c to use the
newer event_channel_op (which takes an int argument instead of an
evtchn_op_t), but then our kernel binary wouldn't run on older
versions of Xen3.

I doubt it, because of this:
#define __XEN_LATEST_INTERFACE_VERSION__ 0x00030204
