\\param filp file pointer.
\\param vma virtual memory area.
\\return zero on success or a negative number on failure.

If the virtual memory area has no offset associated with it then it's a DMA
area, so calls \fBmmap_dma\fR\&. Otherwise searches the map in drm_device::maplist,
checks that the restricted flag is not set, sets the virtual memory operations
according to the mapping type and remaps the pages. Finally sets the file
pointer and calls \fBvm_open\fR\&.
