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?

The PowerPC port, except for a couple of processors (4xx and 8xx again)
could never use virt_to_phys on any dynamically allocated (vmalloc()'ed)
space.  All of the drivers/devices that used these macros were using
ioremapped() or static buffers.  Perhaps the PCI mapping functions are
implementing some of this, and I need to take a look.
