These changes make xenpaging work for me.
The first one is a fix for a bug I introduced shortly before leaving for
vacation. Currently the guest will hang because the ring fills up when the
balloon driver removes pages.
The second one avoids a crash during BIOS startup.
The third one is another version of the machine_to_phys_mapping[] handling.
The fourth is only required when the balloon driver is used in the guest.
The fifth implements a config option to allow an automated start of
xenpaging for a given guest.
And the last one lists some action items for xenpaging.

As of now, xenpaging will either crash the hypervisor or the guest due
to page-out of low memory. Perhaps the building of xenpaging could be
disabled in the Makefile?

Olaf
