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.

It's unclear from "Submitting Patches" documentation that Reported-by
is not supposed to be used against new features. (It's more clear
in the section 5.4 "Patch formatting and changelogs" of the "A guide
to the Kernel Development Process", where it suggests that change
should fix something existing in the kernel. Clarify the Reported-by
usage in the "Submitting Patches".

The RTLA documents were added to Documentation/ but never hooked into the
rest of the docs build, leading to a bunch of warnings like:
Documentation/tools/rtla/rtla-osnoise.rst: WARNING: document isn't included in any toctree
Add some basic glue to wire these documents into the build so that they are
available with the rest of the rendered docs. No attempt has been made to
turn the RTLA docs into proper RST files rather than warmed-over man pages;
that is an exercise for the future.

Patch series "remove Xen tmem leftovers".
Since the removal of the Xen tmem driver in 2019, the cleancache hooks
are entirely unused, as are large parts of frontswap. This series
against linux-next (with the folio changes included) removes
cleancaches, and cuts down frontswap to the bits actually used by zswap.
This patch (of 13):
The cleancache subsystem is unused since the removal of Xen tmem driver
in commit 814bbf49dcd0 ("xen: remove tmem driver").

The YAML DT encoding has leaked into some array properties. Properties
which are defined as an array should have a schema that's just an array.
That means there should only be a single level of 'minItems',

"The highlight is the new mount "device" string syntax implemented by
Venky Shankar. It solves some long-standing issues with using
different auth entities and/or mounting different CephFS filesystems
from the same cluster, remounting and also misleading /proc/mounts
contents. The existing syntax of course remains to be maintained.
On top of that, there is a couple of fixes for edge cases in quota and
a new mount option for turning on unbuffered I/O mode globally instead
of on a per-file basis with ioctl(CEPH_IOC_SYNCIO)"

- sit: allow encapsulated IPv6 traffic to be delivered locally
- axienet: fix init/reset handling, add missing barriers, read the
right status words, stop queues correctly

This patchset allows to have a single kernel for sv39 and sv48 without
being relocatable.
The idea comes from Arnd Bergmann who suggested to do the same as x86,
that is mapping the kernel to the end of the address space, which allows
the kernel to be linked at the same address for both sv39 and sv48 and
then does not require to be relocated at runtime.
This implements sv48 support at runtime. The kernel will try to boot
with 4-level page table and will fallback to 3-level if the HW does not
support it. Folding the 4th level into a 3-level page table has almost
no cost at runtime.
Note that kasan region had to be moved to the end of the address space
since its location must be known at compile-time and then be valid for
both sv39 and sv48 (and sv57 that is coming).
* riscv-sv48-v3:
riscv: Explicit comment about user virtual address space size
riscv: Use pgtable_l4_enabled to output mmu_type in cpuinfo
riscv: Implement sv48 support
asm-generic: Prepare for riscv use of pud_alloc_one and pud_free
riscv: Allow to dynamically define VA_BITS
riscv: Introduce functions to switch pt_ops
riscv: Split early kasan mapping to prepare sv48 introduction
riscv: Move KASAN mapping next to the kernel mapping
riscv: Get rid of MAXPHYSMEM configs

Now that KASAN_SHADOW_OFFSET is defined at compile time as a config,
this value must remain constant whatever the size of the virtual address
space, which is only possible by pushing this region at the end of the
address space next to the kernel mapping.
