    I'm not a kernel dev, but I noted that pmap_unmapcontig doesn't
take into consideration when va is NULL; I know it's bad driver
programming if uncontig is implicitly called with NULL, but there
should be some error handling or something here (a NULL deref will
occur in pmap_qremove, which will cause a panic).
Thanks,
