From: Anshuman Khandual <anshuman.khandual@xxxxxxx> Subject: mm/memory_hotplug: rename all existing 'memhp' into 'mhp' This renames all 'memhp' instances to 'mhp' except for memhp_default_state for being a kernel command line option. This is just a clean up and should not cause a functional change. Let's make it consistent rater than mixing the two prefixes. In preparation for more users of the 'mhp' terminology.
