    None of the exported headers after 'make headers_install' have definition
    of DECLARE_BITMAP macro. It is defined in include/linux/types.h which is
    different from include/uapi/linux/types.h and missing this definition and
    a few other things.

    One option would be add DECLARE_BITMAP macro to include/uapi/linux/types.h
    and add include/linux/bitops.h to uapi.

    Thoughts?
