From: "Luis R. Rodriguez"
The S390 architecture requires a custom pci_iomap() implementation
as the asm-generic implementation assumes there are disjunctions
between PCI BARs, and on S390 PCI BAR are not disjunctive, S390 requires
the bar parameter in order to find the corresponding device and cr
18 matches
