To support movable memory nodes (CONFIG_MOVABLE_NODE), at least one of the following must be true: 1. We're on x86. This arch has the capability to identify movable nodes at boot by parsing the ACPI SRAT, if the movable_node option is used. 2. Our config supports memory hotplug, which means that a movable node can be created by hotplugging all of its memory into ZONE_MOVABLE. Fix the Kconfig definition of CONFIG_MOVABLE_NODE, which currently recognizes (1), but not (2).
We now enable a lot of new code on different arch, such as the new node list N_MEMORY. Reviewed-by: Aneesh Kumar K.V <redacted>
