Souptick Joarder df9bde015a xen/gntdev.c: convert to use vm_map_pages()
Convert to use vm_map_pages() to map range of kernel memory to user vma.

map->count is passed to vm_map_pages() and internal API verify map->count
against count ( count = vma_pages(vma)) for page array boundary overrun
condition.
