Zoltan Menyhart 98075d245a [IA64] Fix NUMA configuration issue
There is a NUMA memory configuration issue in 2.6.24:

A 2-node machine of ours has got the following memory layout:

Node 0:	0 - 2 Gbytes
Node 0:	4 - 8 Gbytes
Node 1:	8 - 16 Gbytes
Node 0:	16 - 18 Gbytes

"efi_memmap_init()" merges the three last ranges into one.

"register_active_ranges()" is called as follows:

efi_memmap_walk(register_active_ranges, NULL);

i.e. once for the 4 - 18 Gbytes range. It picks up the node
number from the start address, and registers all the memory for
the node #0.

"register_active_ranges()" should be called as follows to
make sure there is no merged address range at its entry:

efi_memmap_walk(filter_memory, register_active_ranges);

"filter_memory()" is similar to "filter_rsvd_memory()",
but the reserved memory ranges are not filtered out.
