[Xen-devel] [PATCH v5 4/8] xen: make grant resource limits per domain

Instead of using the same global resource limits of grant tables (max. number of grant frames, max. number of maptrack frames) for all domains make these limits per domain. This will allow setting individual limits in the future. For now initialize the per domain limits with the global values.
