Before doing so, please be aware of the WIP at http://git.infradead.org/users/dwmw2/linux-andd.git This is the support for DMA mapping for ACPI devices. Largely thrown together on a plane above the Atlantic over the last day, so mostly untested, but a lot of it is fairly simply switching to using 'struct device' instead of assuming 'struct pci_dev' everywhere. For now I've taken the simple approach of using the ->devices array, and *expanding* it to contain the bus+devfn to use for ACPI devices too. -- dwmw2
