- * bitmaps provide an array of bits, implemented using an
- * array of unsigned longs.  The number of valid bits in a
- * given bitmap does _not_ need to be an exact multiple of
- * BITS_PER_LONG.
- *
- * The possible unused bits in the last, partially used word
- * of a bitmap are 'don't care'.  The implementation makes
- * no particular effort to keep them zero.  It ensures that
- * their value will not affect the results of any operation.
- * The bitmap operations that return Boolean (bitmap_empty,
- * for example) or scalar (bitmap_weight, for example) results
- * carefully filter out these unused bits from impacting their
- * results.
- *
- * These operations actually hold to a slightly stronger rule:
- * if you don't input any bitmaps to these ops that have some
- * unused bits set, then they won't output any set unused bits
- * in output bitmaps.
- *
- * The byte ordering of bitmaps is more natural on little
- * endian architectures.
