Considering that fb_defio is utterly broken without the fix (writing
the frame buffer makes the VM endlessly invoke vm_ops.page_mkwrite()),
wouldn't it make sense to merge the fix even if it

If the drivers/video/fb_defio.c hunk of that patch fixes something then I'd
be inclined to merge the whole thing - adding a new driver

Deferred I/O was utterly broken. Reading the mmap()ed framebuffer
worked, but writing it made the VM endlessly invoke
vm_ops.page_mkwrite(). That happened because we failed to set
page-mapping and page-index.
The fix is to set them, and clean up properly before the framebuffer
gets released.
