Subject: mm: create /sys/kernel/mm
From: Nishanth Aravamudan <nacc@xxxxxxxxxx>
Add a kobject to create /sys/kernel/mm when sysfs is mounted. The kobject
will exist regardless. This will allow for the hugepage related sysfs
directories to exist under the mm "subsystem" directory. Add an ABI file
appropriately.
