Christophe Leroy f265512582 powerpc/32s: Move _tlbie() and _tlbia() in a new file
_tlbie() and _tlbia() are used only on 603 cores while the
other functions are used only on cores having a hash table.

Move them into a new file named nohash_low.S

Add mmu_hash_lock var is used by both, it needs to go
in a common file.

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.
