remap_file_pages protection support: ia64 bits
EDESC
From: Ingo Molnar <mingo@elte.hu>

I've attached a 'blind' port of the prot bits of fremap to ia64.  I've
compiled it with a cross-compiler but otherwise it's untested.  (and it's
very likely i got the pte bits wrong - but it's roughly OK.)

This should at least make ia64 compile.
