857898eb4b selftests: mptcp: add missing join check
This function also writes the name of the test with its ID, making clear
a new test has been executed.

Without that, the ADD_ADDR results from this test was appended at the
end of the previous test causing confusions. Especially when the second
test was failing, we had:

  17 signal invalid addresses     syn[ ok ] - synack[ ok ] - ack[ ok ]
                                  add[ ok ] - echo  [ ok ]
                                  add[fail] got 2 ADD_ADDR[s] expected 3

In fact, this 17th test was OK but not the 18th one.

Now we have:

  17 signal invalid addresses     syn[ ok ] - synack[ ok ] - ack[ ok ]
                                  add[ ok ] - echo  [ ok ]
  18 signal addresses race test   syn[fail] got 2 JOIN[s] syn expected 3
   - synack[fail] got 2 JOIN[s] synack expected
   - ack[fail] got 2 JOIN[s] ack expected 3
                                  add[fail] got 2 ADD_ADDR[s] expected 3

4f9bf2a2f5 tcp: Don't acquire inet_listen_hashbucket::lock with disabled BH.
Commit
   9652dc2eb9 ("tcp: relax listening_hash operations")

removed the need to disable bottom half while acquiring
listening_hash.lock. There are still two callers left which disable
bottom half before the lock is acquired.

On PREEMPT_RT the softirqs are preemptible and local_bh_disable() acts
as a lock to ensure that resources, that are protected by disabling
bottom halves, remain protected.
This leads to a circular locking dependency if the lock acquired with
disabled bottom halves is also acquired with enabled bottom halves
followed by disabling bottom halves. This is the reverse locking order.
It has been observed with inet_listen_hashbucket:🔒

local_bh_disable() + spin_lock(&ilb->lock):
  inet_listen()
    inet_csk_listen_start()
      sk->sk_prot->hash() := inet_hash()
	local_bh_disable()
	__inet_hash()
	  spin_lock(&ilb->lock);
	    acquire(&ilb->lock);

Reverse order: spin_lock(&ilb2->lock) + local_bh_disable():
  tcp_seq_next()
    listening_get_next()
      spin_lock(&ilb2->lock);
	acquire(&ilb2->lock);

  tcp4_seq_show()
    get_tcp4_sock()
      sock_i_ino()
	read_lock_bh(&sk->sk_callback_lock);
	  acquire(softirq_ctrl)	// <---- whoops
	  acquire(&sk->sk_callback_lock)

Drop local_bh_disable() around __inet_hash() which acquires
listening_hash->lock. Split inet_unhash() and acquire the
listen_hashbucket lock without disabling bottom halves; the inet_ehash
lock with disabled bottom halves.

ec1c7ad476 cpufreq: CPPC: Fix performance/frequency conversion
CPUfreq governors request CPU frequencies using information
on current CPU usage. The CPPC driver converts them to
performance requests. Frequency targets are computed as:
	target_freq = (util / cpu_capacity) * max_freq
target_freq is then clamped between [policy->min, policy->max].

The CPPC driver converts performance values to frequencies
(and vice-versa) using cppc_cpufreq_perf_to_khz() and
cppc_cpufreq_khz_to_perf(). These functions both use two different
factors depending on the range of the input value. For
cppc_cpufreq_khz_to_perf():
- (NOMINAL_PERF / NOMINAL_FREQ) or
- (LOWEST_PERF / LOWEST_FREQ)
and for cppc_cpufreq_perf_to_khz():
- (NOMINAL_FREQ / NOMINAL_PERF) or
- ((NOMINAL_PERF - LOWEST_FREQ) / (NOMINAL_PERF - LOWEST_PERF))

This means:
1- the functions are not inverse for some values:
   (perf_to_khz(khz_to_perf(x)) != x)
2- cppc_cpufreq_perf_to_khz(LOWEST_PERF) can sometimes give
   a different value from LOWEST_FREQ due to integer approximation
3- it is implied that performance and frequency are proportional
   (NOMINAL_FREQ / NOMINAL_PERF) == (LOWEST_PERF / LOWEST_FREQ)

This patch changes the conversion functions to an affine function.
This fixes the 3 points above.

b97cca3ba9 xfs: only bother with sync_filesystem during readonly remount
In commit 02b9984d64, we pushed a sync_filesystem() call from the VFS
into xfs_fs_remount.  The only time that we ever need to push dirty file
data or metadata to disk for a remount is if we're remounting the
filesystem read only, so this really could be moved to xfs_remount_ro.

Once we've moved the call site, actually check the return value from
sync_filesystem.

drop reason is introduced to the tracepoint of kfree_skb. Therefore,
drop_monitor is able to report the drop reason to users by netlink.

The drop reasons are reported as string to users, which is exactly
the same as what we do when reporting it to ftrace.

f647de4b02 Merge branch 'pdf-conversion' into docs-next
PDF-generation improvements from Akira Yokasawa; Akira says:

This patch set improves conversions of DOT -> PDF and SVG -> PDF
for PDF docs.

* DOT -> PDF conversion

Current scheme uses "dot -Tpdf" (of graphviz).

Cons:
  - openSUSE's dot(1) does not support -Tpdf.
  - Other distro's dot(1) generates PDFs with unnecessarily wide
    margins for inclusion into LaTeX docs.

Patch 1/4 changes the route to the following two steps:

  1. DOT -> SVG by "dot -Tsvg"
  2. SVG -> PDF by "rsvg-convert -f pdf" with fallback to convert(1)

Pros:
  - Improved portability across distros
  - Less space around graphs in final PDF documents

Con:
  - On systems without rsvg-convert, generated PDF will be of raster
    image.

Patch 2/4 avoids raster-image PDF by using "dot -Tpdf" on systems where
the option is available.

* SVG -> PDF conversion

Current scheme uses convert(1) (of ImageMagick)

Cons:
  - Generated PDFs are of raster image.  Some of them look blurry.
  - Raster images tend to be large in size.
  - convert(1) delegates SVG decoding to rsvg-convert(1).
    It doesn't cover full range of Inkscape-specific SVG features
    and fails to convert some of SVG figures properly.

Improper conversions are observed with SVGs listed below (incomplete,
conversion quality depends on the version of rsvg-convert):
  - Documentation/userspace-api/media/v4l/selection.svg
  - Documentation/userspace-api/media/v4l/vbi_525.svg
  - Documentation/userspace-api/media/v4l/vbi_625.svg
  - Documentation/userspace-api/media/v4l/vbi_hsync.svg
  - Documentation/admin-guide/blockdev/drbd/DRBD-8.3-data-packets.svg
  - Documentation/admin-guide/blockdev/drbd/DRBD-data-packages.svg

If you have Inkscape installed as well, convert(1) delegates SVG
decoding to inkscape(1) rather than to rsvg-convert(1) and SVGs listed
above can be rendered properly.

So if Inkscape is required for converting those SVGs properly, why not
use it directly in the first place?

Patches 3/4 and 4/4 add code to utilize inkscape(1) for SVG -> PDF
conversion when it is available.  They don't modify any existing
requirements for kernel-doc.

Patch 3/4 adds the alternative route of SVG -> PDF conversion by
inkscape(1).
Patch 4/4 delegates warning messages from inkscape(1) to kernellog.verbose
as they are likely harmless in command-line uses.

Pros:
  - Generated PDFs are of vector graphics.
  - Vector graphics tends to be smaller in size and looks nicer when
    zoomed in.
  - SVGs drawn by Inkscape are fully supported.

On systems without Inkscape, no regression is expected by these two
patches.

8ccd05697a docs: sphinx/kfigure.py: Use inkscape(1) for SVG -> PDF conversion
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.

ecf5fb58cd docs: sphinx/kfigure.py: Add check of 'dot -Tpdf'
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.

c9edbe1eb9 docs: sphinx/kfigure.py: Use rsvg-convert(1) for DOT -> PDF conversion
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.

31fc1c63c2 dt-bindings: clock: Add binding for TI clksel
In order to prepare for fixing lots of devicetree unique_unit_address
warnings for the TI clock nodes, let's add a binding for the TI clksel
clocks. This allows us to move the overlapping reg properties for the
component clocks to be children of the related clksel nodes. And with
that we need the reg property only for the parent clksel node making
the reg property unique like it should be.

We want to set #clock-cells = <2> in case we ever start parsing ranges
of clkcsel instances directly using a clksel driver rather than using the
existing component clock drivers and child nodes.

And before the devicetree files can be updated, we need to update the
TI clock drivers to get the IO address from the parent clksel node.

There is a confusion with regard to the source address of
memcpy_real() and calling functions. While the declared
type for a source assumes a virtual address, in fact it
always called with physical address of the source.

This confusion led to bugs in copy_oldmem_kernel() and
copy_oldmem_user() functions, where __pa() macro applied
mistakenly to physical addresses. It does not lead to a
real issue, since virtual and physical addresses are
currently the same.

and the way it actually used.
