For s390, I'd love to see progress in the consolidation. Feel free to
submit changes for arch/s390x/kernel/ioctl32.c directly, like
Stephen Rothwell does for the syscall32 consolidation. Of course,
Martin has the last word here, but I'm rather sure he agress with me
in this.

If you want access to an s390x system, you can probably get access
to one at http://www-1.ibm.com/servers/eserver/zseries/os/linux/lcds/
or install the hercules emulator. I try to keep working kernel tree
at http://linux-390.bkbits.net/, but the 32 bit emulation has been
broken for most of 2.5.

Note that for any ioctls that pass pointers, you will need special
massaging for the high order bit of the user space pointer, because
s390 only has 31 bit pointers, not 32 bit.
