We never free the ms->usage data for boot memory sections (see section_deactivate()). And to identify whether ms->usage was allocated from memblock, we simply identify it by looking at PG_reserved.
Yep, PageReserved() is already enough to tell that case apart :)
Consequently, there is no need to mark ms->usage as MIX_SECTION_INFO. Let's just stop doing that.
Right, MIX_SECTION_INFO doesn't add much here. For ms->usage, removal code doesn't use MIX_SECTION_INFO at all :)
