Subject: [PATCH] include/linux/memblock.h: Use __init_memblock for movable_node_is_enabled

From: Chen Gang <chengang@...ndsoft.com.cn>

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.
