Add a domctl hypercall to set the domain's resource limits regarding
grant tables. It is accepted only as long as neither
gnttab_setup_table() has been called for the domain, nor the domain
has started to run.

I just realized that this only allows dom0 to set dom0's limit. You
also need to add set_gnttab_limits to the permissions allowed by
create_domain_common in xen.if for this to be useful.
