    right.

    this patch include seperate bootmem.c into bootmem.c and nobootmem.c to reduce
    MACRO according Ingo and others.
    mm/bootmem.c | 165 +----------
    mm/nobootmem.c | 415 +++++++++++++++++++++++++++

    later will
    1. remove x86 own copy for find_from_low_to_high after more testing with high to low. that is about 200 lines code.
    2. replace range.c with lmb. but need to expand lmb little bit
    like add can_resize and can_merge to be attribute of lmb_type.

    Thanks

    Yinghai Lu
