    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.
