RE: show_mem() for ia64 discontig takes a really long time on large systems.

Since we only deal with blocks of memory in IA64_GRANULE_SIZE
pieces (16M or 64M) that would seem to be the natural skip
amount.

Oh, but that is probably still too slow. Jack said he has 180GB
holes ... 180GB/16M = 11520 useless probes and TLB misses.  We'd
be better of to brute force seach the efi_memmap for the next
address when we get a miss.
