Colin Ian King	97a103e6b5	ipmi_si: fix potential integer overflow on large shift ... Shifting unsigned char b by an int type can lead to sign-extension overflow. For example, if b is 0xff and the shift is 24, then top bit is sign-extended so the final value passed to writeq has all the upper 32 bits set. Fix this by casting b to a 64 bit unsigned before the shift.
