If the goal is to put the usemap in the same section as the memory itself, in order to allow for it to be freed during memory hotplug, this new change just makes the facility not work some of the time. Now maybe sometimes it will work, maybe sometimes it will not. It's not the end of the world if this change is reverted for a few days while we work out what to do about this. Really, it does not reflect badly upon you or Goto-san, if the change is reverted temporarily.
