From: "Kirill A. Shutemov" <kirill.shutemov@xxxxxxxxxxxxxxx>
Subject: memblock: fix section mismatch
allmodconfig produces following warning for me:
WARNING: vmlinux.o(.text.unlikely+0x10314): 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.
Let's mark the function with __meminit. It fixes the warning.
