Mike, there was some discussion about this and the other new 'feature

Thanks, I guess I missed that session.

The hypercall transfer page is just one of several new feature flags
that should enable us to have a single xen-ified kernel that is capable
of running on bare metal, on pae and non-pae hypervisors, 64b

A 32-bit kernel running on a 64-bit xen, for example? So in this case xen fills the page with 32-bit hcalls?
