[PATCH] ACPI-based PCI resources: PCMCIA bugfix, but resources missing in trees
Don't auto-configure yenta sockets for PCMCIA devices if it is connected to the root PCI bus on the x86 or x86_64 architectures. Previously, this was handled by the "ioport_resource"/"iomem_resource" check a few lines below, but with the new ACPI-based resource handling this doesn't catch all cases any longer. pci-yenta-cardbus-fix.patch and this patch should solve the initialization time trouble. However, the ACPI-based PCI resource handling is badly broken, IMHO: - many resources of devices don't show up in the resource trees ( /proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but also possibly other subsystems (ISA, PnP, ...) do not know which resources it cannot use. - verify_root_windows() should fail if there are no iomem _or_ ioport resources, not only if there are no iomem _and_ ioport resources.
