Since v9:
- Rebase after a good chunk of patches were merged.
- Review from Thomas:
  - TCG/KVM host query is moved to the start of the series.
  - Changelog for atomics test.
  - Dropped spinlock patch change for now.
  - Fixed tlbie assembly long lines in mmu patch.
  - Use fdt64 accessor for 64-bit dt value.
  - Upgrade powerpc gitlab CI to Fedora 40 and enable more tests
  - Several other improvements.
- Reduced some long lines.
- Fixed some SPDX headers.
- New patch for adding a panic test. s390x is the only other panic
  test user but it requires KVM so I couldn't see if run_tests.sh
  looks sane there, but the harness needed a fix to work on powerpc.

Thanks,
Nick
