[PATCH] PPC64: 32bit wrapper for ioctls.

Hi Paul,
  The patch adds some 32bit wrappers for 2 ioctls that Java needs.
Assuming this doesn't generate a round of discussion, please
forward upstream to akpm/torvalds.

Why add them to arch/ppc64? These don't look architecture specific, so they
should go into include/linux/compat_ioctl.h.

Note that TIOCMIWAIT is not COMPATIBLE_IOCTL, but ULONG_IOCTL. It doesn't make
a difference for ppc64, but if you add it to the generic file that is needed for
s390x.
