Can we straighten out the terminology so it's less confusing please?

and..... can we make a general page_is_ram() function that does what it
says? on x86 it can go via the e820 table, other architectures can do
whatever they need....

That would be very helpful. That should cover the remaining (ab)users
of PageReserved.

It would probably be fastest to implement this with a page flag,
however if swsusp and ioremap are the only users then it shouldn't
be a problem to go through slower lookups (and this would remove the
need for the PageValidRAM flag that I had worried about earlier).

I think swsusp can be modified to use PageNosave only and everything
that is not to be touched by swsusp should be marked as no-save.

Greets,
