Re: Can a page be HighMem without having the HighMem flag set?

That's fine. I'll just ignore those pages for the sake of suspending and
resuming. I've just successfully suspended with those changes, but
suspending is the easy part.... resuming worked too :>

It's the pages efff6000- which are causing me grief. if I understand
things correctly, page_is_ram is returning 0 for those pages, and as a
result they get marked reserved and not HighMem by one_highpage_init.
I suppose, then, that I need to check for and ignore pages >
highstart_pfn where PageHighMem is not set/Reserved is set. (Either
okay?).

If it's reserved, most/all bets are off -- only the "owner" of the thing
understands what it is. Some more formally-defined semantics for reserved
are needed, but 2.6 is unlikely to get them soon.
