While the TIF_SYSCALL_EMU is set in ptrace_resume independent of any architecture, currently only powerpc and x86 unset the TIF_SYSCALL_EMU flag in ptrace_disable which gets called from ptrace_detach. Let's move the clearing of TIF_SYSCALL_EMU flag to __ptrace_unlink which gets executed from ptrace_detach and also keep it along with or close to clearing of TIF_SYSCALL_TRACE.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
