We unconditionally initialize power_off in kvm_arch_vcpu_ioctl_vcpu_init(), and do the same in this patch for mp_state, depending on if KVM_ARM_VCPU_POWER_OFF is set. Any objections to leaving that as-is? I can move the RUNNABLE case into kvm_arch_vcpu_create() as you've suggested, too. -- Thanks, Oliver _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
