Andrey Konovalov 0d3c9468be kasan, arm64: add arch_suppress_tag_checks_start/stop
Add two new tagging-related routines arch_suppress_tag_checks_start/stop
that suppress MTE tag checking via the TCO register.

These rouines are used in the next patch.

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.
