Andy Lutomirski 7d4bb32bc6 x86/entry/64: Move SWAPGS into the common IRET-to-usermode path

commit 8a055d7f411d41755ce30db5bb65b154777c4b78 upstream.

All of the code paths that ended up doing IRET to usermode did
SWAPGS immediately beforehand.  Move the SWAPGS into the common
code.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
