PNP: increase I/O port & memory option address sizes
Bjorn Helgaas [Fri, 27 Jun 2008 22:57:06 +0000 (16:57 -0600)]
ACPI Address Space Descriptors can be up to 64 bits wide.
We should keep track of the whole thing when parsing resource
options, so this patch changes PNP port and mem option
fields from "unsigned short" and "unsigned int" to
"resource_size_t".
