>From arch/ppc64/kernel/iSeries_setup.c:
* The iSeries may have very large memories ( > 128 GB ) and a partition
* may get memory in "chunks" that may be anywhere in the 2**52 real
* address space. The chunks are 256K in size.
Also check out CONFIG_MSCHUNKS code and see why I'd love to see a generic
solution to this problem.
