Ignore earlier message ... I thought I saw a || when you really
just have && all the way through this:

+# define pfn_valid(pfn)		(((pfn) >= min_low_pfn) && ((pfn) < max_low_pfn) && ia64_pfn_valid(pfn))

Doesn't that mean that you are optimizing for the case where some
one passed in a bad pfn ... does that really happen a lot?
