         help
-          KCOV does not have any arch-specific code, but currently it is enabled
-          only for x86_64. KCOV requires testing on other archs, and most likely
-          disabling of instrumentation for some early boot code.
+          An architecture should select this when it can successfully
+          build and run with CONFIG_KCOV. This typically requires
+          disabling instrumentation for some early boot code.
