Revision fc9bbca8f650e5f738af8806317c0a041a48ae4a authored by Linus Torvalds on 19 April 2013, 16:57:35 UTC, committed by Linus Torvalds on 19 April 2013, 16:57:35 UTC 
vm: convert fb_mmap to vm_iomap_memory() helper
 
This is my example conversion of a few existing mmap users.  The
fb_mmap() case is a good example because it is a bit more complicated
than some: fb_mmap() mmaps one of two different memory areas depending
on the page offset of the mmap (but happily there is never any mixing of
the two, so the helper function still works).
