We had similar problems with other ioctls where userspace did things like that. What we did there was to put the compat handler to generic code. The patch below does that, adding a big comment about what's going on and removing the COMPAT_IOCTL entires for these on powerpc that not only weren't ever useful but are duplicated now aswell.
