Christian Borntraeger 9778385db3 sched: fix accounting of interrupts during guest execution on s390 ... Currently the scheduler checks for PF_VCPU to decide if this timeslice has to be accounted as guest time. On s390 host interrupts are not disabled during guest execution. This causes theses interrupts to be accounted as guest time if CONFIG_VIRT_CPU_ACCOUNTING is set. Solution is to check if an interrupt triggered account_system_time. As the tick is timer interrupt based, we have to subtract hardirq_offset. I tested the patch on s390 with CONFIG_VIRT_CPU_ACCOUNTING and on x86_64. Seems to work.
