It would also be nice to convert ARM to using sparsemem rather than
discontigmem, but despite having a patch adding the supporting common
infrastructure for the last year and a half or so, no one in the ARM
community is interested in it.
Since I've no machines which use the present discontig support and
have more than a single bank of memory, I've no way to test and
progress sparsemem on ARM - and since no one's interested I'm probably
going to drop the ARM sparsemem git branch soon.
