Yijing Wang 8fb878c5f1 s390/MSI: Use standard mask and unmask funtions ... MSI irqchip in s390 has its own mask and unmask MSI irq functions, zpci_enable_irq() and zpci_disable_irq(). They mask and unmask MSI irq in standard ways, no arch special. MSI driver provides two global standard functions mask_msi_irq() and unmask_msi_irq(). Local zpci_enable_irq() and zpci_disable_irq() are almost the same as the standard two. the difference is local mask/unmask functions read the mask status before mask and unmask everytime. Then change the value and rewrite to hardware. In standard functions, save the mask status after mask and unmask msi irq, and use the cached status to change the mask status. When we mask or unmask a MSI irq, we always cache its mask status except we know need not to cache it, like in pci_msi_shutdown. So use the standard functions to replace the local is safe.
