Heiko Carstens b771aeac32 [S390] Fix IRQ tracing. ... If a machine check is pending and the external or I/O interrupt handler returns to userspace io_mcck_pending is going to call s390_handle_mcck. Before this happens a call to TRACE_IRQS_ON was already made since we know that we are going back to userspace and hence interrupts will be enabled. So there was an indication that interrupts are enabled while in reality they are still disabled. s390_handle_mcck will do a local_irq_save/restore pair and confuse lockdep which later complains about inconsistent irq tracing. To solve this just call trace_hardirqs_off before calling s390_handle_mcck and trace_hardirqs_on afterwards.
