Andrey Konovalov 8479d7b5be kasan: documentation updates
Update KASAN documentation:

 - Bump Clang version requirement for HW_TAGS as ARM64_MTE depends on
   AS_HAS_LSE_ATOMICS as of commit 2decad92f4731 ("arm64: mte: Ensure
   TIF_MTE_ASYNC_FAULT is set atomically"), which requires Clang 12.

 - Add description of the new kasan.vmalloc command line flag.

 - Mention that SW_TAGS and HW_TAGS modes now support vmalloc tagging.

 - Explicitly say that the "Shadow memory" section is only applicable to
   software KASAN modes.

 - Mention that shadow-based KASAN_VMALLOC is supported on arm64.

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.
