I too do not understand why it makes sense to move PTRACE_SET_SYSCALL into the common kernel/ptrace.c. To me the fact that PTRACE_SET_SYSCALL can be undefined and syscall_set_nr() is very much arch-dependant (but most probably trivial) means that this code should live in arch_ptrace(). In any case, I think it doesn't make sense to pass task_pt_regs(child), this helper can do this itself if it needs struct pt_regs.
