Mark Rutland ba884534f1 arm64: Kconfig: Make SME depend on BROKEN for now 
commit 81235ae0c8 upstream.

Although support for SME was merged in v5.19, we've since uncovered a
number of issues with the implementation, including issues which might
corrupt the FPSIMD/SVE/SME state of arbitrary tasks. While there are
patches to address some of these issues, ongoing review has highlighted
additional functional problems, and more time is necessary to analyse
and fix these.

For now, mark SME as BROKEN in the hope that we can fix things properly
in the near future. As SME is an OPTIONAL part of ARMv9.2+, and there is
very little extant hardware, this should not adversely affect the vast
majority of users.

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.
