Subject: [PATCH v4 RESEND 0/7] Handle faults in KUnit tests

Hi,

This patch series teaches KUnit to handle kthread faults as errors, and
it brings a few related fixes and improvements.

Shuah, everything should be OK now, could you please merge this series?

All these tests pass (on top of v6.8):
/tools/testing/kunit/kunit.py run --alltests
/tools/testing/kunit/kunit.py run --alltests --arch x86_64
/tools/testing/kunit/kunit.py run --alltests --arch arm64 \
  --cross_compile=aarch64-linux-gnu-

I also built and ran KUnit tests as a kernel module.

A new test case check NULL pointer dereference, which wasn't possible
before.

This is useful to test current kernel self-protection mechanisms or
future ones such as Heki: https://github.com/heki-linux
