Note that the early boot debugging problems go away with gcc-4.2.4.  My
problem now (what I [maybe incorrectly] believe) is stack overflow with
NR_CPUS=4096 and a specific random config file.

Btw, I've completed the first half of splitting the zero_based_fold into
zero_based_only and fold_pda_into_percpu and am testing that now.
