[kvm-unit-tests PATCH 0/6] powerpc improvements

[Chinmay Rath <rathc@linux.ibm.com>]

This series aims to add a couple of new powerpc tests and improve the
powerpc build structure.

This is originally Nick's work. The last version (v10) of which can be seen here :
https://lore.kernel.org/linuxppc-dev/20240612052322.218726-1-npiggin@gmail.com/
Couple of patches from the series are already merged.

Since it has been 2 years since this series was posted, I originally
posted this as a RFC. This v1 series has changes accomodating the review comments
received in the RFC :
https://lore.kernel.org/kvm/20260602064806.3101025-1-rathc@linux.ibm.com/

I have rebased the patches to the upstream state.
For the patches which did not require any changes in the existing upstream code,
I have retained the "Reviewed-by"s and "Acked-by" (patch 3,5 & 6) from
Nick's series. I have also added Andrew's "Reviewed-by" received on
patch 2 in the RFC. Nick had originally introduced powernv tests as well.
Removed it for now since it was causing CI failure in the current upstream.

Change log from RFC :
1. Patch 2: Added Andrew's "Reviewed-by".
2. Patch 4: Removed usage of gitlab-ci group to run test - Thomas
   It would be nice to make use of the gitlab-ci group, but doing the
   change of all archs would make sense in a separate series. I look
   forward to doing that.
3. Patch 6: Removed addition of panic test in gitlab-ci group - Thomas

There was a discussion on the build failing in Travis CI with Clang, in the
RFC, which I have addressed there.

Nicholas Piggin (6):
  powerpc: add pmu tests
  configure: Make arch_libdir a first-class entity
  powerpc: Remove remnants of ppc64 directory and build structure
  powerpc: gitlab CI update
  scripts/arch-run.bash: Fix run_panic() success exit status
  powerpc: Add a panic test
