[PATCH] mod_devicetable.h fixes * ieee1394_device_id has kernel_ulong_t field after an odd number of __u32 ones. Since mod_devicetable.h is included both from kernel and from host build helper, we may be in trouble if we are building on 32bit host for 64bit target - userland sees unsigned long long, kernel sees unsigned long and while their sizes match, alignments might not. Fixed by forcing alignment. Fortunately, almost nobody else needs that - the rest of such fields is naturally aligned as it is. * of_device_id has void * in it. Host userland helpers need kernel_ulong_t instead, since their void * might have nothing to do with the kernel one. Fixed in the same way it's done for similar problems in pcmcia_device_id (ifdef __KERNEL__). * pcmcia_device_id has the same problem as ieee1394_device_id. Fixed the same way.
