Has anybody ever looked into implementing that? What architectures
besides MIPS could take advantage of such a feature?
We already use it on Sparc64 for mmap()'ing the frame buffers, we
could easily extend it to work for mmap()'s of real memory. Check out
arch/sparc64/mm/generic.c in the vger CVS tree for details.
