The sphinx-pre-install supports installing sphinx via a virtual
environment using pip/pypi or directly from the distribution's
package, when --no-virtualenv is used.

However, even when --no-virtualenv, the current logic is
still recomending to install a virtual env, due to a regression.

It turns that the logic there is complex, as it depends on
several different conditions.

Split the code which recommends Sphinx on two separate
functions, in order to clean up the code.

The description of those vars produce this warning:
  Documentation/ABI/testing/sysfs-bus-iio:799: WARNING: Inline emphasis start-string without end-string.

Due to an asterisk, which is the markup for emphasis. One possible
fix would be to use ``*_timeout`` to avoid it, but looking at
the descriptions of other fields in this file, a common pattern
is to refer to "these" when talking about the API calls that
are described.

So, change the text in order to preserve the meaning while
avoiding the need of using an asterisk there.

Activating xeCJK in English and Italian-translation documents
results in sub-optimal typesetting with wide-looking apostrophes
and quotation marks.

The xeCJK package provides macros for enabling and disabling its
effect in the middle of a document, namely \makexeCJKactive and
\makexeCJKinactive.

So the goal of this change is to activate xeCJK in the relevant
chapters in translations.

To do this:

    o Define custom macros in the preamble depending on the
      availability of the "Noto Sans CJK" font so that those
      macros can be used regardless of the use of xeCJK package.

    o Patch \sphinxtableofcontents so that xeCJK is inactivated
      after table of contents.

    o Embed those custom macros in each language's index.rst file
      as a ".. raw:: latex" construct.

Note: A CJK chapter needs \kerneldocCJKon in front of its chapter
heading, while a non-CJK chapter should have \kerneldocCJKoff
below its chapter heading.

This is to make sure the CJK font is available to CJK chapter's
heading and ending page's footer.

Tested against Sphinx versions 2.4.4 and 4.0.2.

While include/linux/bitops.h brings in the BIT() macro, it was moved to
include/linux/bits.h in commit 8bd9cb51 ("locking/atomics, asm-generic:
Move some macros from <linux/bitops.h> to a new <linux/bits.h> file").

Since that commit BIT() has moved again into include/vdso/bits.h via
commit 3945ff37 ("linux/bits.h: Extract common header for vDSO").

I think the move to the vDSO header can be considered an implementation
detail, so for now update the checkpatch documentation to recommend use
of include/linux/bits.h.

What happens is that 3 drivers use the same pattern to report
max and dim setting for different ambient light zones.

It should be noticed that the adp8870 doc was missing an
entry for l1_daylight_dim, which was fixed on this patch.

While the ambient light zone is device-specific, the sysfs
