Looked at the gntdev (grant table mappings for user space) driver,
noticed that one is not self-contained.  It needs a hook for page unmapping:

  http://xenbits.xensource.com/xen-3.1-testing.hg?rev/7180d2e61f92
  plus an s/ptep_get_and_clear_full/zap_pte/ fixup a few changesets
  later.

Upstreaming that one could become *uhm* intresting.  Nevertheless the
gntdev functionality is quite useful for writing pure userspace
backend drivers ...

cheers,
  Gerd
