Say Y here to disable hardware tracing in some known "jumpy" pieces
of code so that the trace buffer will extend further back.

+ This option enables special console drivers which allow the kernel
+ to print messages very early in the bootup process.
+ This is useful for kernel debugging when your machine crashes very
+ early before the console code is initialized. After enabling this
+ feature, you must add "earlyprintk=serial,uart0,57600" to the
+ command line (bootargs). It is safe to say Y here in all cases, as
+ all of this lives in the init section and is thrown away after the
+ kernel boots completely.
