+ Selecting this options disables use of the mprofile-kernel ABI for
+ kernel tracing. That will cause options such as live patching
+ (CONFIG_LIVEPATCH) which depend on CONFIG_DYNAMIC_FTRACE_WITH_REGS to
+ be disabled also.
+
+ If you have a toolchain which supports mprofile-kernel, then you can
+ enable this. Otherwise leave it disabled. If you're not sure, say
+ "N".
