Michael Ellerman 5eb7cfb3a2 selftests/powerpc: Add a test of bad (out-of-range) accesses
Userspace isn't allowed to access certain address ranges, make sure we
actually test that to at least some degree.

This would have caught the recent bug where the SLB fault handler was
incorrectly called on an out-of-range access when using the Radix MMU.
It also would have caught the bug we had in get_region_id() where we
were inserting SLB entries for bad addresses.

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.
