-         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
-         disable this. Otherwise leave it enabled. If you're not sure, say
-         "Y".
