    SubjectRe: passing my own compiler options into linux kernel compiling
    Quoth Michal Semler:

    Although it might be handled differently elsewhere, this snippet
    from gcc/toplev.c suggests -O4 buys you nothing you don't get from
    -O3:

    if (optimize >= 3)
    {
    flag_inline_functions = 1;
    flag_rename_registers = 1;
    }
