Stafford Horne 6dfd85ada8 openrisc: Properly store r31 to pt_regs on unhandled exceptions
[ Upstream commit 812489ac4dd91144a74ce65ecf232252a2e406fb ]

In commit 91993c8c2e ("openrisc: use shadow registers to save regs on
exception") the unhandled exception path was changed to do an early
store of r30 instead of r31.  The entry code was not updated and r31 is
not getting stored to pt_regs.

This patch updates the entry handler to store r31 instead of r30.  We
also remove some misleading commented out store r30 and r31
instructrions.

I noticed this while working on adding floating point exception
handling,  This issue probably would never impact anything since we kill
the process or Oops right away on unhandled exceptions.

Fixes: 91993c8c2e ("openrisc: use shadow registers to save regs on exception")

README

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.
