Also, it assumes that it will be mapping pages for only one xbd request
at a time; see XENSHM_MAX_PAGES_PER_REQUEST.  That will need some
adjusting if I want to piece together a whole MAXPHYS... and, while I'm
in this file, I wonder: is xen_shm's big piece of VM actually big enough
to handle use by both disk and net devices?

Oh, and: it's nice that the value of xen_shm_size is patchable, but
won't the size of _xen_shm_vaddr2ma[] be a little harder to manipulate
post-linking?
