virt inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8URKX -------------------------------- If we set kvm-arm.vtimer_irqbypass=1, we need to probe mbigen driver before kvm_arm_init, since the vtimer mbigen regs should be set before kvm_arm_init flush the value of vtimer_irqbypass. Otherwise the regs of vtimer mbigen may not be set correctly, and kvm will set vtimer_irqbypass=0.
