       [#7] If, within a  translation  unit,  the  same  identifier
       appears   with  both  internal  and  external  linkage,  the
       behavior is undefined.

"early_printk" has this type of behaviour in printk.c. Attached/appended patch removes the dependency on the behaviour of the compiler.

thanks,
