Right. To be clear, the background info I put in the commit log refers to x86, where the SRAT can describe movable nodes which exist at boot. They're trying to avoid allocations from those nodes before they've been identified.
On power, movable nodes can only exist via hotplug, so that scenario can't happen. We can immediately go back to top-down allocation. That is the missing call being added in the patch.
Can we fix cmdline_parse_movable_node() to do the right thing? I suspect that code is heavily x86 only in the sense that no other arch needs it.
