Nobody has said we should discount lowmem rss when dealing with a GFP_DMA
allocation, it simply wasn't possible until the lowmem rss counters were
introduced in -mm. It would prevent the needless killing of innocent
tasks which would not allow the page allocation to succeed, so it's a good
feature to have. It doesn't need to be configurable at all, we just need
to find a way to introduce it into the heuristic without mangling oom_adj.
