This kselftest next update for Linux 6.9-rc1 consists of:
-- livepatch restructuring to move the module out of lib to be
built as a out-of-tree modules during kselftest build. This
change makes it easier change, debug and rebuild the tests by
running make on the selftests/livepatch directory, which is not
currently possible since the modules on lib/livepatch are build
and installed using the main makefile modules target.
-- livepatch restructuring fixes for problems found by kernel test
robot. The change skips the test if kernel-devel isn't installed
(default value of KDIR), or if KDIR variable passed doesn't exists.
-- resctrl test restructuring and new non-contiguous CBMs CAT test
-- new ktap_helpers to print diagnostic messages, pass/fail tests
based on exit code, abort test, and finish the test.
-- a new test verify power supply properties.
-- a new ftrace to exercise function tracer across cpu hotplug.
-- timeout increase for mqueue test to allow the test to run on
i3.metal AWS instances.
-- minor spelling corrections in several tests.
-- missing gitignore files and changes to existing gitignore files.

Move bash helpers for outputting in KTAP format to the common selftests
folder. This allows kselftests other than the dt one to source the file
and make use of the helper functions.
Define pass, fail and skip codes in the same file too.

When walking directory trees, instead of looking for specific files and
running dirname to get the parent folder, traverse all folders and
ignore the ones not containing the desired files. This avoids the need
to call dirname inside the loop, which drastically decreases run time:
Running locally on a mt8192-asurada-spherion, which reports 160 test
cases, has gone from 5.5s to 2.9s, while running remotely with an
nfsroot has gone from 13.5s to 5.5s.
This change has a side-effect, which is that the root DT node now
also shows in the output, even though it isn't expected to bind to a
driver. However there shouldn't be a matching driver for the board
compatible, so the end result will be just an extra skipped test:
ok 1 / # SKIP

Introduce a new kselftest to detect devices that were declared in the
Devicetree, and are expected to be probed by a driver, but weren't.
The test uses two lists: a list of compatibles that can match a
Devicetree device to a driver, and a list of compatibles that should be
ignored. The first is automatically generated by the
dt-extract-compatibles script, and is run as part of building this test.
The list of compatibles to ignore is a hand-crafted list to capture the
few exceptions of compatibles that are expected to match a driver but
not be bound to it.
