[PATCH] ieee1394: raw1394: Add ioctl() for 32bit userland on 64bitkernel, amendment

From: Stefan Richter
Date: Mon May 21 2007 - 12:52:49 EST


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.
