I've picked up 1-7 and am build testing now.

I'm not happy about the /proc/devicetree stuff in this patch.  I would
rather see the proc_device_tree_init() call moved to initcall time
so that the need for an of_pdt_init_devicetree() hook goes away, but
there are a number of gotchas for dynamic tree users that I need to
investigate.  Anyway, I'll get 1-7 tested and into linux-next while I
think about patch 8.
