Yes. so If you look at the file that Steve referenced, many of the tty ioctrls we define for the other archtectures don't occur. Also, I noticed that in the ARM linux.hh, the constants look a little questionable to me. It almost looks like they were copied and pasted from another architecture, and then a couple of them were changed to be ARM specific.
