ieee1394: raw1394: Add ioctl() for 32bit userland on 64bit kernel, amendment
Pointed out by Arnd Bergmann: PPC32 aligns this at 64bit, IA32 packs it. A kernel-wide available __compat_u64 which is 4-byte aligned on AMD64 and IA64 would be nicer though. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
