Niklas Schnelle df057c914a s390/pci: Fix unexpected write combine on resource ... In the initial MIO support introduced in commit 71ba41c9b1 ("s390/pci: provide support for MIO instructions") zpci_map_resource() and zpci_setup_resources() default to using the mio_wb address as the resource's start address. This means users of the mapping, which includes most drivers, will get write combining on PCI Stores. This may lead to problems when drivers expect write through behavior when not using an explicit ioremap_wc().
