Right, I don't see an obvious need elsewhere so it could be a flag
specific to nomap, tho it still needs to be taken into account in the
main allocation code.

But which node ? :-)

I'd rather you add a new API, no need to change the call sites:

Add foo_node(xxx,node); and have the existing foo() be implemented
as a static inline calling foo_node(xxx,0); or something like that, then
I can change the powerpc code to use the later & pass the PCI device
node (which should be in the pci_controller structure). We can add more
later.

Ok, let me know.
