No PTRACE_READDATA for archs other than SPARC?

Hi,
I was trying to understand ptrace code in kernel. It seems there's
no PTRACE_READDATA for architectures other than sparc and sparc64.
There's a function named ptrace_readdata() in kernel/ptrace.c but I
couldn't find a way to invoke it from user space. Is the feature
missing? or Is it intended?
Another thing I noticed, the prototype for do_ptrace() in
arch/sparc/kernel/ptrace.c is

asmlinkage void do_ptrace(struct pt_regs *regs)

I thought it should be some thing like
asmlinkage int sys_ptrace(long request, long pid, long addr, long
data)

It would be great if some one can answer it.

Thank You,
Pradeep Padala
