This isn't a criticism of your patch, but I think the drmem.c code
should be moved into platforms/pseries.
That would then make most of it private to platforms/pseries and we
wouldn't need to export things in arch/powerpc/include/asm.
I don't have an issue with moving it to platform/pseries. I originally
put it in arch/powerpc/mm because the numa code also uses the drmem code.
Yeah, originally the NUMA code was only used on pseries so the
distinction between NUMA and pseries-specific NUMA didn't exist.
But these days we're getting more and more code that is really pseries
(or PAPR) specific, so it might make sense to move it.
I may be wrong, perhaps there isn't a clean split there, but it would be
worth trying.
