Hi!
This is next version of ioctl32 consolidation. At one point it
compiled on x86-64 and sparc64. I'm not 100% sure it still does...
Could you try to apply it on your architecture, fix whatever breakage
it causes, and submit patch back to me?
ia64 has very different ioctl32 emulation (and very short). What is
going on there? Also not all architectures knew about
register_ioctl32_translation. Ouch.
