Enable HAVE_ARCH_KCSAN on all powerpc platforms, permitting use of the kernel concurrency sanitiser through the CONFIG_KCSAN_* kconfig options. Boots and passes selftests on 32-bit and 64-bit platforms. See documentation in Documentation/dev-tools/kcsan.rst for more information.

So that's a followup of a not yet posted version v5 of the other series ? Why not just add patch 1 in that series and have KCSAN for all powerpc at once ?
