cd238effef docs: kbuild: convert docs to ReST and rename to *.rst
The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.

Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

8ea618899b docs: cdrom: convert docs to ReST and rename to *.rst
The stuff there is almost already at ReST format. A
conversion for them is trivial: just add a missing titles
and fix some scape codes for them to match ReST syntax.

While here, rename the cdrom-standard.txt, with was converted
from LaTeX to ReST on the previous patch, and add it to the
index file.

e327cfcb25 docs: cdrom-standard.tex: convert from LaTeX to ReST
This is the only LaTeX documentation file inside the documentation.

Instead of having a Latex document directly there, convert
it to ReST format, as this is the format we're using for docs.

For now, let's keep the extension as .txt in order to avoid
warnings when building the documentation with Sphinx.

The next patch patch will rename it to .rst and add it to the
building system.

Another round of SPDX header file fixes for 5.2-rc4
 
 These are all more "GPL-2.0-or-later" or "GPL-2.0-only" tags being
 added, based on the text in the files.  We are slowly chipping away at
 the 700+ different ways people tried to write the license text.  All of
 these were reviewed on the spdx mailing list by a number of different
 people.
 
 We now have over 60% of the kernel files covered with SPDX tags:

 	Files checked:            64533
 	Files with SPDX:          40392
 	Files with errors:            0

    Documentation/networking/dsa/sja1105.rst:91: WARNING: Block quote ends without a blank line; unexpected unindent.

It will still produce a table, but the html output is wrong, as
it won't interpret the second line as the continuation for the
first ones, because identation doesn't match.

After the change, the output looks a way better and we got rid
of two warnings.

	04578dd330 ("Define AF_ISDN and PF_ISDN")
	e4ac9bc1f6 ("Add mISDN driver")

None of them added a Documentation/isdn/mISDN.cert file.
Also, whatever were supposed to be written there on that time,
probably doesn't make any sense nowadays, as I doubt isdn would
have any massive changes.

So, let's just get rid of the broken reference, in order to

Merge tag 'drm-fixes-2019-06-07-1' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "A small bit more lively this week but not majorly so. I'm away in
  Japan next week for family holiday, so I'll be pretty disconnected,
  I've asked Daniel to do fixes for the week while I'm out.

  The nouveau firmware changes are a bit large, but they address a big
  problem where a whole set of boards don't load with the driver, and
  the new firmware fixes that, so I think it's worth trying to land it
  now.

  core:
   - Allow fb changes in async commits (drivers as well)

  udmabuf:
   - Unmap scatterlist when unmapping udmabuf

  nouveau:
   - firmware loading fixes for secboot firmware on new GPU revision.

  komeda:
   - oops, dma mapping and warning fixes

  arm-hdlcd:
   - clock fixes
   - mode validation fix

  i915:
   - Add a missing Icelake workaround
   - GVT - DMA map fault fix and enforcement fixes

   - DCE resume fix
   - New raven variation updates"

49b8095867 i2c: xiic: Add max_read_len quirk
This driver does not support reading more than 255 bytes at once because
the register for storing the number of bytes to read is only 8 bits. Add
a max_read_len quirk to enforce this.

This was found when using this driver with the SFP driver, which was
previously reading all 256 bytes in the SFP EEPROM in one transaction.
This caused a bunch of hard-to-debug errors in the xiic driver since the
driver/logic was treating the number of bytes to read as zero.
Rejecting transactions that aren't supported at least allows the problem
to be diagnosed more easily.

893a7d32e8 lockref: Limit number of cmpxchg loop retries
The lockref cmpxchg loop is unbound as long as the spinlock is not
taken. Depending on the hardware implementation of compare-and-swap
a high number of loop retries might happen.

Add an upper bound to the loop to force the fallback to spinlocks
after some time. A retry value of 100 should not impact any hardware
that does not have this issue.

With the retry limit the performance of an open-close testcase
improved between 60-70% on ThunderX2.

d93445225c uaccess: add noop untagged_addr definition
Architectures that support memory tagging have a need to perform untagging
(stripping the tag) in various parts of the kernel. This patch adds an
untagged_addr() macro, which is defined as noop for architectures that do
not support memory tagging. The oncoming patch series will define it at
least for sparc64 and arm64.
