With the current wording readers might infer that PR_GET_TAGGED_ADDR_CTRL
will report the mode currently active in the thread however this is not the
actual behaviour, instead all modes currently selected by the process will
be reported with the mode used depending on the combination of the
requested modes and the default set for the current CPU. This has been the
case since 433c38f40f ("arm64: mte: change ASYNC and SYNC TCF settings
into bitfields"), before that we did not allow more than one mode to be
requested simultaneously.
Update the documentation to more clearly reflect current behaviour.

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.
