Pull x86 MDS mitigations from Thomas Gleixner:
"Microarchitectural Data Sampling (MDS) is a hardware vulnerability
which allows unprivileged speculative access to data which is
available in various CPU internal buffers. This new set of misfeatures
has the following CVEs assigned:
CVE-2018-12126 MSBDS Microarchitectural Store Buffer Data Sampling
CVE-2018-12130 MFBDS Microarchitectural Fill Buffer Data Sampling
CVE-2018-12127 MLPDS Microarchitectural Load Port Data Sampling
CVE-2019-11091 MDSUM Microarchitectural Data Sampling Uncacheable Memory
MDS attacks target microarchitectural buffers which speculatively
forward data under certain conditions. Disclosure gadgets can expose
this data via cache side channels.
Contrary to other speculation based vulnerabilities the MDS
vulnerability does not allow the attacker to control the memory target
address. As a consequence the attacks are purely sampling based, but
as demonstrated with the TLBleed attack samples can be postprocessed
successfully.
The mitigation is to flush the microarchitectural buffers on return to
user space and before entering a VM. It's bolted on the VERW
instruction and requires a microcode update. As some of the attacks
exploit data structures shared between hyperthreads, full protection
requires to disable hyperthreading. The kernel does not do that by
default to avoid breaking unattended updates.
The mitigation set comes with documentation for administrators and a
deeper technical view"

The Microarchitectural Data Sampling (MDS) vulernabilities are mitigated by
clearing the affected CPU buffers. The mechanism for clearing the buffers
uses the unused and obsolete VERW instruction in combination with a
microcode update which triggers a CPU buffer clear when VERW is executed.
Provide a inline function with the assembly magic. The argument of the VERW
instruction must be a memory operand as documented:
"MD_CLEAR enumerates that the memory-operand variant of VERW (for
example, VERW m16) has been extended to also overwrite buffers affected
by MDS. This buffer overwriting functionality is not guaranteed for the
register operand variant of VERW."
Documentation also recommends to use a writable data segment selector:
"The buffer overwriting occurs regardless of the result of the VERW
permission check, as well as when the selector is null or causes a
descriptor load segment violation. However, for lowest latency we
recommend using a selector that indicates a valid writable data
segment."
Add x86 specific documentation about MDS and the internal workings of the
mitigation.

There is currently very little documentation in the kernel on maintainer
level tasks. In particular there are no documents on creating pull
requests to submit to Linus.
Quoting Greg Kroah-Hartman on LKML:
Anyway, this actually came up at the kernel summit / maintainer
meeting a few weeks ago, in that "how do I make a
good pull request to Linus" is something we need to document.
Here's what I do, and it seems to work well, so maybe we should turn
it into the start of the documentation for how to do it.
(quote references: kernel summit, Europe 2017)
Create a new kernel documentation book 'how to be a maintainer'
(suggested by Jonathan Corbet). Add chapters on 'configuring git' and
'creating a pull request'.
Most of the content was written by Linus Torvalds and Greg Kroah-Hartman
in discussion on LKML. This is stated at the start of one of the
chapters and the original email thread is referenced in
'pull-requests.rst'.

Having the kernel-documentation at the topmost level doesn't
allow generating a separate PDF file for it. Also, makes harder
to add extra contents. So, place it on a sub-dir.

A simple conversion of alsa-driver-api document from DocBook to ReST.
It's moved to the new Documentation/sound/kernel-api subdirectory that
will contain other ALSA kernel API documents.
The GPL legal note was removed, as it's superfluous (and doesn't fit
with ReST kernel docs pretty well).

Transitioned the tpm_vtpm_proxy documentation to the Sphinx
infrastructure and removed parts from the documentation that are easier
to pull from the sources. Restructured vtpm_proxy.h and tpm_vtpm_proxy.c
to be compatible with this approach and wrote associated documentation
comments.

The creation of the admin and process guides is a great thing, but, without
care, we risk replacing a messy docs directory with a few messy Sphinx
books. In an attempt to head that off and show what I'm thinking, here's a
set of tweaks that, I think, make the existing Sphinx-formatted docs a bit
more accessible.
This will be the initial landing point for readers, so give them a bit of
introductory material. Also split the TOC into area-specific chunks to
make the whole thing a bit more approachable.

Add minimal conf.py and moved dev-tools/tools.rst to dev-tools/index.rst
makes the dev-tools folder buildable stand-alone. To build only this
folder run::
make SPHINXDIRS=dev-tools htmldocs
make SPHINXDIRS=dev-tools pdfdocs

Place README, REPORTING-BUGS, SecurityBugs and kernel-parameters
on an user's manual book.
As we'll be numbering the user's manual, remove the manual
numbering from SecurityBugs.

As we'll type this a lot, after adding CodingStyle & friends,
let's rename the directory name to a shorter one.

This is just a very basic conversion, I've split up the original
multi-book template, and also split up the multi-part mac80211
part in the original book; neither of those were handled by the
automatic pandoc conversion.
Fix errors that showed up, resulting in a much nicer rendering,
at least for the interface combinations documentation.

Now that the files at Documentation/development-process/
were converted to ReST, make create a book at Sphinx.
As we'll have other books related to the development process,
we'll add it as a sub-book.

We don't need to keep it as a single large file anymore; split it up so
that it is easier to manage and the individual sections can be read
directly as plain files.
