No, I was looking at my local kernel tree for an old project, which is
considerably older.  But looking at the official tree now, it looks like I
might have patched the get_unmapped_area support directly into there myself
at some point.  It does work though.

I guess to properly support FB mmap, someone will have to add
HAVE_ARCH_FB_UNMAPPED_AREA support into arch/m68k, probably in a manner
similar to the bfin implementation.  Or just provide a default !MMU
implementation the way I did.

Though just accessing smem_start directly works too -- but again, assumes
that you can rewrite the application.
