Log Message:
Fix 3w-9xxx to use PCI resources properly and work under Xen (bug #309611)
linux-2.6-3w-9xxx-mem_len.patch:
--- NEW FILE linux-2.6-3w-9xxx-mem_len.patch ---

Subject: 3w-9xxx: use PCI resource lenght correctly
Trying to ioremap() a larger area than pci_resource_len()
may fail (e.g. under Xen). Fixes 3w-9xxx to use pci_resource_len()
as length parameter to ioremap() instead of PAGE_SIZE.
