Merge KASAN updates from Andrew Morton.
This adds a new hardware tag-based mode to KASAN. The new mode is
similar to the existing software tag-based KASAN, but relies on arm64
Memory Tagging Extension (MTE) to perform memory and pointer tagging
(instead of shadow memory and compiler instrumentation).
By Andrey Konovalov and Vincenzo Frascino.

This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.
The new mode won't be using shadow memory, but will still use the concept
of memory granules. Each memory granule maps to a single metadata entry:
8 bytes per one shadow byte for generic mode, 16 bytes per one shadow byte
for software tag-based mode, and 16 bytes per one allocation tag for
hardware tag-based mode.
Rename KASAN_SHADOW_SCALE_SIZE to KASAN_GRANULE_SIZE, and
KASAN_SHADOW_MASK to KASAN_GRANULE_MASK.
Also use MASK when used as a mask, otherwise use SIZE.
No functional changes.

by default (not available with GCC and makes x86 unbootable with Clang).
Disable unreachable when objtool is in use (redundant and confuses things:
instrumentation appears at unreachable locations).

...
Generic KASAN also supports to record the last two workqueue stacks and
print them in KASAN report. So that need to update documentation.

usage.rst goes into a detailed section about faking out classes, but
currently lacks wording about how one might idiomatically test a range
of inputs.
Add a new chapter for "Common Patterns" and group "Isolating behvaior"
and this new section under there.
Give an example of how one might test a hash function via macros/helper
funcs and a table-driven test and very briefly discuss pros and cons.
Also highlight the KUNIT_EXPECT_*_MSG() variants (that aren't mentioned
elsewhere [1]) which are particularly useful in these situations.
It is also criminally underused at the moment, only appearing in 2
tests (both written by people involved in KUnit).

This Kunit update for Linux 5.10-rc1 consists of:
- add Kunit to kernel_init() and remove KUnit from init calls entirely.
This addresses the concern Kunit would not work correctly during
late init phase.
- add a linker section where KUnit can put references to its test suites.
This patch is the first step in transitioning to dispatching all KUnit
tests from a centralized executor rather than having each as its own
separate late_initcall.
- add a centralized executor to dispatch tests rather than relying on
late_initcall to schedule each test suite separately. Centralized
execution is for built-in tests only; modules will execute tests when
loaded.
- convert bitfield test to use KUnit framework
- Documentation updates for naming guidelines and how kunit_test_suite()
works.
- add test plan to KUnit TAP format

Pull documentation updates from Mauro Carvalho Chehab:
"A series of patches addressing warnings produced by make htmldocs.
This includes:
- kernel-doc markup fixes
- ReST fixes
- Updates at the build system in order to support newer versions of
the docs build toolchain (Sphinx)
After this series, the number of html build warnings should reduce
significantly, and building with Sphinx 3.1 or later should now be
supported (although it is still recommended to use Sphinx 2.4.4).
As agreed with Jon, I should be sending you a late pull request by the
end of the merge window addressing remaining issues with docs build,
as there are a number of warning fixes that depends on pull requests
that should be happening along the merge window.
The end goal is to have a clean htmldocs build on Kernel 5.10.
PS. It should be noticed that Sphinx 3.0 is not currently supported,
as it lacks support for C domain namespaces. Such feature, needed in
order to document uAPI system calls with Sphinx 3.x, was added only on
Sphinx 3.1"

This kselftest update for Linux 5.10-rc1 consists of enhancements to
-- speed up headers_install done during selftest build
-- add generic make nesting support
-- add support to select individual tests:
- Selftests build/install generates run_kselftest.sh script to run
selftests on a target system. Currently the script doesn't have
support for selecting individual tests. Add support for it.
With this enhancement, user can select test collections (or tests)
individually. e.g:
run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep
Additionally adds a way to list all known tests with "-l", usage
with "-h", and perform a dry run without running tests with "-n".

Which Sphinx 3, :c:type: can't be used anymore for structs,
as this should be used only for typedefs.
Rely on automarkup.py for struct references.
This file has an special case, though: it uses the tag also
to point to an array. Let's use, instead, :c:expr: for such
purpose, as it should do the right thing.
This should fix this warning:

kmemleak-test.c is just a kmemleak test module, which also can not be used

Pull v5.9 KCSAN bits from Paul E. McKenney.
Perhaps the most important change is that GCC 11 now has all fixes in place
to support KCSAN, so GCC support can be enabled again.
Signed-off-by: Ingo Molnar <mingo@kernel.org>
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Sparse's home page used to be a wiki (sparse.wiki.kernel.org)
but this wiki only contained a short intro and the release notes.
But nowadays, sparse's main page is sparse.docs.kernel.org,
which contains all what was in the wiki but also other documentation,
mainly oriented about sparse's internals.
So, add a link to this in the kernel documentation.
