This patchset solves the same problem as my previous one[1] but follows
a rather different approach. Instead of implementing DISCONTIGMEM for
PowerPC32, I simply switched the "is this RAM" check in __ioremap_caller
to the existing page_is_ram function, and unified page_is_ram to search
memblock.memory on PPC64 and PPC32.

The intended result is, as before, that my Wii can allocate the MMIO
range of its GPIO controller, which was previously not possible, because
the reserved memory hack (__allow_ioremap_reserved) didn't affect the
API in kernel/resource.c.

Thanks to Christophe Leroy for reviewing the previous patchset.

I tested your new serie, it doesn't break my 8xx so it is OK for me.

Thanks for testing it!
