    /* Somewhere in the middle of the GCC 2.96 development cycle, we implemented
    a mechanism by which the user can annotate likely branch directions and
    expect the blocks to be reordered appropriately. Define __builtin_expect

    shrinks my 3.2.1-compiled kernel text by about 64 kbytes:

    text data bss dec hex filename

    3249255 555436 727204 4531895 4526b7 vmlinux-after

    mnm:/tmp> nm vmlinux-before|grep __constant_c_and_count_memset | wc
    233 699 9553
    mnm:/tmp> nm vmlinux-after|grep __constant_c_and_count_memset | wc
    13 39 533
    Can anyone see a problem with it?
