[IA64] point saved_max_pfn to the max_pfn of the entire system

Browse source

Make saved_max_pfn point to max_pfn of entire system.

Without this patch is so that vmcore is zero length on ia64.  This is
because saved_max_pfn was wrongly being set to the max_pfn of the crash
kernel's address space, rather than the max_pfg on the physical memory of
the machine - the whole purpose of vmcore is to access physical memory that
is not part of the crash kernel's addresss space.
