While replacing 'memhp' as 'mhp' in this series, noticed there are
some more 'memhp' scattered around the code from earlier. A mix of
both 'memhp' and 'mhp' might not be a good idea. Hence should we
just change these remaining 'memhp' as 'mhp' as well and possibly
also MEMHP_MERGE_RESOURCE as suggested earlier, in a subsequent
clean up patch ? Would there be a problem with memhp_default_state
being a command line parameter ?
