c637693b20 ubsan: remove UBSAN_MISC in favor of individual options
Make each UBSAN option individually selectable and remove UBSAN_MISC which
no longer has any purpose.  Add help text for each Kconfig, and include a
reference to the Clang sanitizer documentation.  Disable unsigned overflow
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).

ff6135959a A much quieter cycle for documentation (happily), with, one hopes, the bulk
of the churn behind us.  Significant stuff in this pull includes:
 
  - A set of new Chinese translations
  - Italian translation updates
  - A mechanism from Mauro to automatically format Documentation/features
    for the built docs
  - Automatic cross references without explicit :ref: markup
  - A new reset-controller document
  - An extensive new document on reporting problems from Thorsten
 
 That last patch also adds the CC-BY-4.0 license to LICENSES/dual; there was
 some discussion on this, but we seem to have consensus and an ack from Greg
 for that addition.

1f0e943df6 Documentation: kunit: provide guidance for testing many inputs
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).

7cf726a594 linux-kselftest-kunit-5.10-rc1
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

Merge tag 'linux-kselftest-kunit-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull more Kunit updates from Shuah Khan:

 - add Kunit to kernel_init() and remove KUnit from init calls entirely.

   This addresses the concern that Kunit would not work correctly during
   late init phase.

 - add a linker section where KUnit can put references to its test
   suites.

   This 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

Merge tag 'docs/v5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

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:

      Additionally adds a way to list all known tests with "-l", usage
      with "-h", and perform a dry run without running tests with "-n".

365ff56f08 docs: kgdb.rst: fix :c:type: usages
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:

Pull kunit updates from Shuah Khan:

 - Add a generic kunit_resource API extending it to support resources
   that are passed in to kunit in addition kunit allocated resources. In
   addition, KUnit resources are now refcounted to avoid passed in
   resources being released while in use by kunit.

 - Add support for named resources.

 - Important bug fixes from Brendan Higgins and Will Chen

2324d50d05 It's been a busy cycle for documentation - hopefully the busiest for a
while to come.  Changes include:
 
  - Some new Chinese translations
 
  - Progress on the battle against double words words and non-HTTPS URLs
 
  - Some block-mq documentation
 
  - More RST conversions from Mauro.  At this point, that task is
    essentially complete, so we shouldn't see this kind of churn again for a

  - Lots of typo fixes, warning fixes, and more.

39f65da092 Documentation: kunit: Remove references to --defconfig
The --defconfig option in kunit_tool was removed in [1], but the getting
started and kunit_tool documentation still encouraged its use. Update
those documents to reflect that it's no-longer required, and is the
default behaviour if no .kunitconfig is found.

Also update a couple of places where .kunitconfig is still referred to
as kunitconfig (this was changed in [2]).

4d8c1e0557 docs: gcov: replace links with HTTPS
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.

e68dcd8eac kcsan: Re-add GCC as a supported compiler
GCC version 11 recently implemented all requirements to correctly
support KCSAN:

1. Correct no_sanitize-attribute inlining behaviour:
   https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=4089df8ef4a63126b0774c39b6638845244c20d2

2. --param=tsan-distinguish-volatile
   https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=ab2789ec507a94f1a75a6534bca51c7b39037ce0

3. --param=tsan-instrument-func-entry-exit
   https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=06712fc68dc9843d9af7c7ac10047f49d305ad76

Therefore, we can re-enable GCC for KCSAN, and document the new compiler
requirements.
