Heiko Carstens df7997ab1c [S390] irq: fix service signal external interrupt handling ... Interrupt sources like pfault, sclp, dasd_diag and virtio all use the service signal external interrupt subclass mask in control register 0 to enable and disable the corresponding interrupt. Because no reference counting is implemented each subsystem thinks it is the only user of subclass and sets and clears the bit like it wants. This leads to case that unloading the dasd diag module under z/VM causes both sclp and pfault interrupts to be masked. The result will be locked up system sooner or later. Fix this by introducing a new way to set (register) and clear (unregister) the service signal subclass mask bit in cr0. Also convert all drivers.
