There's no sense in including this header without bitmap.h, and the
latter includes linux/types.h, so no need to include it here again.

If you want to make it more rigorous, you can do like this:

        #ifndef __LINUX_BITMAP_H
        #error "Don't include separately from linux/bitmap.h"
        #endif
