#     powerpc/kcsan: Add KCSAN Support
#     
#     Enable HAVE_ARCH_KCSAN on all powerpc platforms, permitting use of the
#     kernel concurrency sanitiser through the CONFIG_KCSAN_* kconfig options.
#     KCSAN requires compiler builtins __atomic_* 64-bit values, and so only
#     report support on PPC64.
#     
#     See documentation in Documentation/dev-tools/kcsan.rst for more
#     information.
