x86-32: Pass the full resource data to ioremap()
It appears that 64-bit PCI resources cannot possibly ever have worked on x86-32 even when the RESOURCES_64BIT config option was set, because any driver that tried to [pci_]ioremap() the resource would have been unable to do so because the high 32 bits would have been silently dropped on the floor by the ioremap() routines that only used "unsigned long". Change them to use "resource_size_t" instead, which properly encodes the whole 64-bit resource data if RESOURCES_64BIT is enabled. Acked-by: H.
