Subject: [PATCH 1/2] Add arch specific dev_sysdata to struct device
Date: Fri, 10 Nov 2006 17:58:50 +1100	[thread overview]
Message-ID: <1163141930.4982.143.camel@localhost.localdomain> (raw)

Adds an arch specific struct dev_sysdata 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...

Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
