New aarch32 ptrace syscall handler is introduced to avoid run-time
detection of the task type.

What's wrong with the run-time detection? If it's just to avoid a
negligible overhead, I would rather keep the code simpler by avoiding
duplicating the generic compat_sys_ptrace().

Nothing wrong. This is how Arnd asked me to do. You already asked this
question: http://lkml.iu.edu/hypermail/linux/kernel/1604.3/00930.html

If it's still looking weird to you, I can switch back to runtime
ptrace. But I'd like to see Arnd's opinion.

Yury.
