Section 3 says:

   e. The rotate left (circular left shift) operation ROTL^n(x), where x
      is a w-bit word and n is an integer with 0 <= n < w, is defined by

         ROTL^n(X) = (x<<n) OR (x>>(w-n))

It should say:

   e. The rotate left (circular left shift) operation ROTL^n(x), where x
      is a w-bit word and n is an integer with 0 <= n < w, is defined by

         ROTL^n(x) = (x<<n) OR (x>>(w-n))

Notes:

A typo. The function argument has to be x, not X.
