I suppose these should go up through Andrew's linux-mm tree, due to
adding a new pin_user_pages*() variant to gup.c. However, it would be
nice if anyone from IVTV or linux-media could provide some run time
testing, maybe even a Tested-by.

Note that I have only compile-tested these patches, although that does
also include cross-compiling for half a dozen arches.

  mm/gup: introduce pin_user_pages_unlocked
  ivtv: convert get_user_pages() --> pin_user_pages()
