On 32-bit (e.g. with m68k-linux-gnu-gcc-4.1):

    crypto/keywrap.c: In function ‘crypto_kw_decrypt’:
    crypto/keywrap.c:191: warning: integer constant is too large for ‘long’ type
    crypto/keywrap.c: In function ‘crypto_kw_encrypt’:
    crypto/keywrap.c:224: warning: integer constant is too large for ‘long’ type
