Benjamin Herrenschmidt 396a1a5832 [POWERPC] Fix mmap of PCI resource with hack for X ... The powerpc version of pci_resource_to_user() and associated hooks used by /proc/bus/pci and /sys/bus/pci mmap have been broken for some time on machines that don't have a 1:1 mapping of devices (basically on non-PowerMacs) and have PCI devices above 32 bits. This attempts to fix it as well as possible. The rule is supposed to be that pci_resource_to_user() always converts the resources back into a BAR values since that's what the /proc interface was supposed to deal with. However, for X to work on platforms where PCI MMIO is not mapped 1:1, it became a habit of platforms like powerpc to pass "fixed up" values there since X expects to be able to use values from /proc/bus/pci/devices as offsets to mmap of /dev/mem... So we keep that contraption here, causing also /sys/*/resource to expose fully absolute MMIO addresses instead of BAR values, which is ugly, but should still work as long as those are only used to calculate alignment within a page. X is still broken when built 32 bits on machines where PCI MMIO can be above 32-bit space unfortunately.
