Subject: PTRACE: compat_sys_ptrace(PTRACE_TRACEME) lacks arch_ptrace_attach()?

I noticed that commit 6ea6dd93 "ptrace: Call arch_ptrace_attach() when
request=PTRACE_TRACEME" added

	if (!ret)
		arch_ptrace_attach(current);

call to sys_ptrace(PTRACE_TRACEME) but commit c269f196 "x86: compat_sys_ptrace"
did not add that call to compat_sys_ptrace(PTRACE_TRACEME).

If compat_sys_ptrace(PTRACE_ATTACH) needs arch_ptrace_attach(), maybe
compat_sys_ptrace(PTRACE_TRACEME) needs arch_ptrace_attach() as well.
