Indeed, preferring node 0 for bootmem allocation on x86_32 got lost
across the nobootmem changes. I followed the git history and
preferring NODE_DATA(0) goes back to the initial git branch creation
time (2.6.12) and I couldn't find any explanation, and nobody
complained about the changed behavior. hpa, do you know why the code
to prefer node 0 for bootmem allocations was added in the first place?
Maybe we can just remove it?
