When KASAN/KCSAN are enabled clang generates .text.asan/tsan sections.
Because they are not mentioned in the linker script warnings are
generated, and when orphan handling is set to error that becomes a build
error, eg:
ld.lld: error: vmlinux.a(init/main.o):(.text.tsan.module_ctor) is
being placed in '.text.tsan.module_ctor' ld.lld: error:
vmlinux.a(init/version.o):(.text.tsan.module_ctor) is being placed in
'.text.tsan.module_ctor'
Fix it by adding the sections to our linker script, similar to the
generic change made in 848378812e ("vmlinux.lds.h: Handle clang's
module.{c,d}tor sections").

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.
