- Move intrhook stuff into kernel.h - Remove all occurrences of #device <device.h> - Add kernel.h were necessary (nowhere) - delete device.h This file contained the structures for cfdata (old style config) and is no longer used. It was included by most drivers. It confuses the remote debugger as the definition of 'struct device' in device.h is found before the one in bus_private.h.
