patch d58aa8c7b1 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.
