From: Arvind Yadav <arvind.yadav.cs@xxxxxxxxx>
Subject: mm/hugetlb.c: constify attribute_group structures
attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.
