To: Linux Arch list; +Cc: Len Brown, Andrew Morton
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...

I would have done this by creating a single line asm-xxx/device.h containing
#include <asm-generic/device.h>
(except for asm-generic, of course) and then as each architecture implements
its own dev_sysdata, it can flesh out its asm/device.h.
Also, I would use _ASM_<ARCH>_DEVICE_H, but thats just my preference.
Just suggestions.

A lot of archs will add custome things, so I felt it simpler that way,
but I can do it via asm-generic... Anybody else preferring it that
way ?

Because I'm overly lazy, I prefer just cp'ing an identical file to all
asm-* dirs :-) Now I suppose it should be easy to do a little script to
get it "right". I'll look into it for the patch renaming it to
arch_data, I'll try to get that out later this morning.
Ben.
