#     crypto: sm3 - fix undefined shift by >= width of value
#     
#     sm3_compress() calls rol32() with shift >= 32, which causes undefined
#     behavior.  This is easily detected by enabling CONFIG_UBSAN.
#     
#     Explicitly AND with 31 to make the behavior well defined.
#     
#     Fixes: 4f0fc1600edb ("crypto: sm3 - add OSCCA SM3 secure hash")
