Subject: hugetlb: remove CONFIG_SYSFS dependency
From: Nishanth Aravamudan <nacc@xxxxxxxxxx>
I incorrectly made the hugetlb kobject functionality depend on SYSFS, when, in
fact, the kobject functions fully work even with out sysfs. Without sysfs,
there is no interface to manipulate the attributes of the various hugetlb
kobjects, but they still exist.
