[PATCH 25/36] Driver core: add dev_archdata to struct device

Greg KH

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Add arch specific dev_archdata to struct device

Adds an arch specific struct dev_arch to struct device. This enables
architecture to add specific fields to every device in the system, like
DMA operation pointers, NUMA node ID, firmware specific data, etc...
