Subject: [PATCH] hugetlb: Fix section mismatch warning in hugetlb.c

    The patch titled hugetlb-add-per-node-hstate-attributes.patch introduces
 the following section mismatch warning, due to a reference form non-init
function hugetlb_register_node to a init function hugetlb_sysfs_add_hstate.

LD      mm/built-in.o
WARNING: mm/built-in.o(.text+0x5396d): Section mismatch in reference
from the function hugetlb_register_node() to the function
.init.text:hugetlb_sysfs_add_hstate()
The function hugetlb_register_node() references
the function __init hugetlb_sysfs_add_hstate().
This is often because hugetlb_register_node lacks a __init
annotation or the annotation of hugetlb_sysfs_add_hstate is wrong.
