A better fix is for xenbus_map_ring_valloc() to have the prototype:
struct vm_struct *xenbus_map_ring_valloc(struct xenbus_device *, int);
It then returns the vmarea that is allocated, or ERR_PTR() on error.
Then xenbus_unmap_ring_vfree() takes the vmarea rather than vaddr and
we avoid the nasty vmlist scan that cannot be modularised.
There's only one user of these functions right now, so the patch for
this proper fix won't be very big.
