I don't think this is needed (and makes the code needlessly large) - reading the MFNs out of the page table entries during vfree() should be quite fine. Having named vfree() you may already guess that I'd also prefer these to be called vmalloc()/vfree(), the more that I can't see why they're being restricted to the Xen heap (rather than using anonymous domheap allocations).
