I think real_screen_base should be renamed to e.g. "phys_screen_base",
and changed to "unsigned long", so you can drop the above cast (and a few
more while assigning it to fix->smem_start).
This will also expose that ATAFB_EXT is broken, and what needs to be
done to fix it (follow the chain of casts, phys addresses are unsigned long,
virt addresses are void *).
Thanks!
