[PATCH 2/2] powerpc/{32,book3e}: kcsan: Extend KCSAN Support

From: Rohan McLure <hidden>
Date: 2023-02-16 05:11:49
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Michael Ellerman, Linus Torvalds

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.
