Arrange hotpluggable memory as ZONE_MOVABLE will cause NUMA performance decreased
because the kernel cannot use movable memory.
For users who don't use memory hotplug and who don't want to lose their NUMA
performance, they need a way to disable this functionality.
So, if users specify "movablecore=acpi" in kernel commandline, the kernel will
use SRAT to arrange ZONE_MOVABLE, and it has higher priority then original
movablecore and kernelcore boot option.
For those who don't want this, just specify nothing.
