The related warning:
LD mm/built-in.o
WARNING: mm/built-in.o(.text.unlikely+0x155d): Section mismatch in reference
from the function movable_node_is_enabled() to the variable
.meminit.data:movable_node_enabled
The function movable_node_is_enabled() references
the variable __meminitdata movable_node_enabled.
This is often because movable_node_is_enabled lacks a __meminitdata
annotation or the annotation of movable_node_enabled is wrong.
