Fix sparc64 MAP_FIXED handling of framebuffer mmaps
patch d58aa8c7b1cc0add7b03e26bdb8988d98d2f4cd1 in mainline.

Subject: [PATCH] [SPARC64]: pass correct addr in get_fb_unmapped_area(MAP_FIXED)
Looks like the MAP_FIXED case is using the wrong address hint. I'd
expect the comment "don't mess with it" means pass the request
straight on through, not change the address requested to -ENOMEM.
