As LaTeX macros for CJK font settings can have Latin-script font
settings as well, settings under Documentation/translations/ can
be moved to the main conf.py.
By this change, translations.pdf built by top-level "make pdfdocs"
can have properly aligned ascii-art diagrams except for Korean
ones.
For the reason of remaining misalignment in Korean diagrams, see
changelog of commit a90dad8f610a ("docs: pdfdocs: Add conf.py
local to translations for ascii-art alignment").

On systems without "Noto Sans CJK" fonts, CJK chapters in
translations.pdf are full of "TOFU" boxes, with a long build time and
a large log file containing lots of missing-font warnings.
Avoid such waste of time and resources by skipping CJK chapters when
CJK fonts are not available.
To skip whole chapters, change the definition of
\kerneldocBegin{SC|TC|KR|JP} commands so that they can have an argument
to be ignored.
This works as far as the argument (#1) is not used in the command.
In place of skipped contents, put a note on skipped contents at the
beginning of the PDF.
Change the call sites in index.rst of CJK translations accordingly.
When CJK fonts are available, existing command definitions with
no argument just work. LaTeX engine will see additional pairs of
"{" and "}", which add a level of grouping without having any effect
on typesetting.

Korean (Hangul) titles in Table of Contents of translations.pdf
don't have inter-phrase spaces.
This is because the CJKspace option of xeCJK is disabled by
default.
Restore the spaces by enabling the option at the beginning of every
document and disable it in the \kerneldocBegin{SC|TC|JP} commands.

xeCJK is enabled in Table of Contents (TOC) so that translations.pdf
built by top-level "make pdfdocs" can have its TOC typeset properly.
This causes quotation marks and apostrophe symbols appear too wide in
Latin-script docs.
This is because (1) Sphinx converts ASCII symbols into multi-byte
UTF-8 ones in LaTeX and (2) in the SC variant of "Noto CJK" font
families, those UTF-8 symbols have full-width glyph.
The KR variant of the font families has half-width glyph for those
symbols and TOC pages should look nicer when it is used instead.
Switch the default CJK font families to the KR variant and teach
xeCJK of those symbols' widths.
To compensate the switch, teach xeCJK of the width in the SC and
TC variants.

Sphinx has its own set of width parameters of Table of Contents (TOC)
for LaTeX defined in its class definition of sphinxmanual.cls.
It also inherits parameters for chapter entries from report.cls of
original LaTeX base.
However, they are optimized assuming small documents with tens of
pages and chapters/sections of less than 10.
To cope with some of kernel-doc documents with more than 1000
pages and several tens of chapters/sections, definitions of those
parameters need to be adjusted.
Unfortunately, those parameters are hard coded in the class
definitions and need low-level LaTeX coding tricks to redefine.
As Sphinx 1.7.9 does not have \sphinxtableofcontentshook,
which defines those parameters in later Sphinx versions,
for compatibility with both pre-1.8 and later Sphinx versions,
empty the hook altogether and redefine \@pnumwidth, \l@chapter,
\l@section, and \@subsection commands originally defined in
report.cls.
Summary of parameter changes:
Width of page number (\@pnumwidth): 1.55em -> 2.7em
Width of chapter number: 1.5em -> 1.8em
Indent of section number: 1.5em -> 1.8em
Width of section number: 2.6em -> 3.2em
Indent of subsection number: 4.1em -> 5em
Width of subsection number: 3.5em -> 4.3em
Notes:
1. Parameters for subsection become relevant only when
":maxdepth: 3" is specified under "toctree::" (e.g., RCU/index.rst).
They can hold subsection numbers up to 5 digits such as "18.7.13"
(in RCU.pdf).
2. Number of chapters in driver-api.pdf is getting closer to 100.
When it reaches 100, another set of tweaks will be necessary.
3. The low-level LaTeX trick is mentioned in "Unofficial LaTeX2e
reference manual" at:

It turns out that LaTeX enables \write18, which allows (some) shell
commands to be executed from the document source, by default. This the
often-seen warning during a pdfdocs build:
restricted \write18 enabled
That is a potential security problem and is entirely unnecessary; nothing
in the kernel PDF docs build needs that capability. So disable \write18
explicitly.

Depending on its version, distro config, and system-setup type,
inkscape(1) emits various warning messages which are harmless in
command-line uses.
List of such warning messages (incomplete, long ones wrapped):
- Gtk-Message: hh:mm:ss.nnn: Failed to load module "canberra-gtk-module"
- Unable to init server: Could not connect: Connection refused
- Failed to get connection
- ** (inkscape:xxx): CRITICAL **: hh:mm:ss.nnn: dbus_g_proxy_new_for_name:

To avoid unnecessary anxiety, capture the message and output it via

Using convert(1) of ImageMagick for SVG -> PDF conversion results in
PDFs containing raster (bitmap) images which sometimes look blurry.
Ideally speaking, SVG to PDF conversion should retain vector graphics
in SVG.
rsvg-convert(1) can do such conversions with regard to SVG files
generated by dot(1).
Unfortunately, rsvg-convert(1) does not cover some of SVG features
specific to Inkscape.
inkscape(1) of Inkscape naturally covers such SVG features.
So add a route in svg2pdf() so that inkscape(1) is used when it is
available.
Note:
After this change, if you have Inkscape installed, ImageMagick nor
librsvg are not required.

To prevent any regression on existing build systems, limit the
fallback of converting DOT -> raster PDF only when both of the
following conditions are met.
o dot(1) doesn't support -Tpdf
o rsvg-convert(1) is not found
While we are here, add kernellog.verbose messages related to
rsvg-convert, 'dot -Tpdf', and 'dot -Tsvg' commands.

On openSUSE, dot(1) command does not support direct PDF output.
On other distros, generated PDF images have unnecessarily wide margins,
especially for small graphs.
By using dot(1) for DOT -> SVG, then rsvg-convert(1) for SVG -> PDF,
more optimal PDF images can be obtained, with the bonus of improved
portability across various distros.
Add rules in kfigure.py so that the above mentioned route is taken
when rsvg-convert(1) is available.
Note that rsvg-convert(1) is recommended by sphinx_pre_install.
So it is most likely that existing systems for building pdfdocs have
rsvg-convert(1) installed.
Note:
SVG features supported by rsvg-convert(1) vary depending on its
version and distro config.
For example, the one found on Ubuntu Bionic (version 2.40.20) does
poor job in rendering some of SVG files drawn by Inkscape.
SVG files generated by dot(1) are converted nicely even with such
old versions of rsvg-convert.
So this change does not affect the quality of such figures in any
way.

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.
Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

Add a test which allows us to test parsing an event alias with hyphens.
Since these events typically do not exist on most host systems, add the
alias to the fake pmu.
Function perf_pmu__test_parse_init() has terms added to match known test
aliases.

Add a test for aliases with hyphens in the name to ensure that the
pmu-events tables are as expects. There should be no reason why these sort
of aliases would be treated differently, but no harm in checking.

Event aliasing for events whose name in the form foo-bar-baz is not
supported, while foo-bar, foo_bar_baz, and other combinations are, i.e.
two hyphens are not supported.
The HiSilicon D06 platform has events in such form:
$ ./perf list sdir-home-migrate
List of pre-defined events (to be used in -e):
uncore hha:
sdir-home-migrate
[Unit: hisi_sccl,hha]
$ sudo ./perf stat -e sdir-home-migrate
event syntax error: 'sdir-home-migrate'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event>event selector. use 'perf list' to list available events
To support, add an extra PMU event symbol type for "baz", and add a new
rule in the bison file.

A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.
Before said patch:
perf record -c 10000 -e arm_spe_0// -- sleep 1
Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.
This patch restores the previous behaviour for non-libpfm4 events.
Fixes: ae5dcc8abe31 (“perf record: Prevent override of attr->sample_period for libpfm4 events”)

Perf script was failed to print the phys_addr for SPE profiling.
One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR
attribute set, perf script then exits with error.
Now referring to 'addr', use evsel__do_check_stype() to check the type.
Before:
# perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
# perf script -F pid,tid,addr,phys_addr
Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field.
After:
# perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
# perf script -F pid,tid,addr,phys_addr
