+ movablecore=acpi [KNL,X86] The SRAT (System Resource Affinity
+ Table) in ACPI provides the NUMA info of the system.
+ And also, there is a Hotpluggable field in the memory
+ affinity of the table specifying which memory is
+ hotpluggable. This option enables the kernel to arrange
+ hotpluggable memory in SRAT as ZONE_MOVABLE.
+ NOTE: Any node which the kernel resides in will
+ always be un-hotpluggable so that the kernel
+ will always have enough memory to boot.
