Make KMSAN usable by adding the necessary Kconfig bits. Signed-off-by: Alexander Potapenko <glider@google.com> --- This patch was previously called "kmsan: Changing existing files to enable KMSAN builds". Logically unrelated parts of it were split away. v4: - split away changes to init/main.c as requested by Andrey Konovalov v6: - moved Makefile changes to the core patch Link: https://linux-review.googlesource.com/id/I1d295ce8159ce15faa496d20089d953a919c125e
