[kvm-unit-tests RFC 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/

Since it has been 2 years since this series was posted, I am now
posting it as a RFC. Couple of patches from the series were already merged.
Posting the rest.

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), and have
removed the same for the ones which required changes in the existing upstream
code during rebase (patch 2). Nick had originally introduced powernv tests as well.
Removed it for now since it was causing CI failure in the current upstream.

Link to Gitlab pipeline :

Please note that the build-centos8 test is failing due to a recent
upstream change unrelated to this patch series.

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
