I'm working on that.  The PowerPC port cheated by using BATs and
trivial macros, but this doesn't work on some of the newer processors
and more complex applications.  Other architectures did the same, and
I am surprised there aren't generic kernel functions to track down this
information.  In fact, these functions are already present for 4xx and
8xx processors, so don't write anything new.

AFAIK such tricks are used for mapping normal (low) memory and ioremapped
areas. For normal memory you can use phys_to_virt()/virt_to_phys() and for
ioremapped memory, you have to store the physical and virtual address
yourself. What am I missing?
