[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.
