We have two implementations of the compat_ioctl handling for ATM, the one that we have had for ages in fs/compat_ioctl.c and the one added to net/atm/ioctl.c by David Woodhouse. Unfortunately, both versions are incomplete, and in practice we use a very confusing combination of the two. For ioctl numbers that have the same identifier on 32 and 64 bit systems, we go directly through the compat_ioctl socket operation, for those that differ, we do a conversion in fs/compat_ioctl.c. This patch moves both variants into the vcc_compat_ioctl() function, while preserving the current behaviour. It also kills off the COMPATIBLE_IOCTL definitions that we never use here. Doing it this way is clearly not a good solution, but I hope it is a step into the right direction, so that someone is able to clean up this mess for real.
