Arnaldo Carvalho de Melo 6bc7626c04 tools headers: Synchronize sound/asound.h
To pick up the changes from this cset:

  823dbb6eb0 ("ALSA: pcm: add SNDRV_PCM_FORMAT_{S,U}20")

It doesn't affect how the tools are built, this os done just to silence
this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/sound/asound.h' differs from latest version at 'include/uapi/sound/asound.h'

Right now tools/perf uses this header to generate string tables to
translate ioctl commands in 'perf trace', see
tools/perf/trace/beauty/sndrv_pcm_ioctl.sh, here is an example
of a strace like system wide session, for one second:

  # perf trace -a -e ioctl sleep 1

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
