Linus Torvalds d451b075f7 Merge tag 'linux_kselftest-next-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull kselftest update from Shuah Khan:

 - livepatch restructuring to move the module out of lib to be built as
   a out-of-tree modules during kselftest build. This 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.
