I thought it looked a bit broken, but I stuck the call in there anyway since it was obviously missing. One of the other things my patch does is move all the functionally identical inlined do_profile functions out of the architecture-specific directories and into linux/sched.h, where the other prof stuff is. It would be nice to get this into the official kernel to prevent the problem recurring.

I assume you mean the ARM-specific version rather than Alan's kernel here?
