[S390] allow setting of upper 32 bit in smp_ctl_set_bit
The bit shift operation in smp_ctl_set_bit does not specify the type of the shifted bit so integer is used as default. Therefore it is not possible to set bits in the upper 32 bit of the control register if the kernel runs in 64 bit mode. Fix this by specifying the type as unsigned long.
