Description:

Fix for warning:
linux/crypto/fcrypt.c:143:47: warning: signed shift result (0x598000000) requires 36 bits to
      represent, but 'int' only has 32 bits [-Wshift-overflow]
        Z(0xef), Z(0x70), Z(0xcf), Z(0xc2), Z(0x2a), Z(0xb3), Z(0x61), Z(0xad),
                                                     ^~~~~~~
linux/crypto/fcrypt.c:113:29: note: expanded from macro 'Z'
                            ^  ~~
linux/include/uapi/linux/byteorder/little_endian.h:38:53: note: expanded from macro
      '__cpu_to_be32'
                                                    ^
linux/include/uapi/linux/swab.h:116:21: note: expanded from macro '__swab32'
        ___constant_swab32(x) :                 \
                           ^
linux/include/uapi/linux/swab.h:18:12: note: expanded from macro '___constant_swab32'
        (((__u32)(x) & (__u32)0x0000ff00UL) <<  8) |            \
                  ^

Solution - make sure we don't exceed the 32 bit range.
 #define Z(x) cpu_to_be32(((x & 0x1f) << 27) | (x >> 5))
