Avoid confusing two different things:
- the WDT I/O region size ('iosize')
- at which offset the SoC map the WDT ('offset')
While it is often the same, we can map smaller region sizes
at larger offsets.
Here we are interested in the I/O region size, so rename as
'iosize'.

This just initializes the basic Xen support in KVM for now. Only permitted

The HVMOP_set_evtchn_upcall_vector hypercall sets the per-vCPU upcall

This takes precedence over the system-wide delivery method set by the

Extract requests, return ENOSYS to all of them. This is enough to allow

matter much what.

The hookup to event channel is a bit of a special case hack right now; as
we make this work for real PV driver back ends, that will be implemented
for the general case of Dom0 ports binding to DomU.

The setup_data links are appended to the compressed kernel image. Since
the kernel image is typically loaded at 0x10, setup_data lives at
