Re: [PATCH 01/10] mm/page-flags: introduce PageHighMemZone()

I don't think the names are very good. I'd keep PageHighMem for the
existing highmem zone, and add something like PageDirectMapped or
similar for ay page that has a valid direct mapping address. This will
also come in handy if we plan to go ahead with the xpfo work.
