    Per the text in  Documentation/SubmitChecklist as below, we should
    explicitly have header linux/errno.h in localtimer.h for ENXIO
    reference.
    
    1: If you use a facility then #include the file that defines/declares
       that facility.  Don't depend on other header files pulling in ones
       that you use.
    
    Otherwise, we may run into some compiling error like the following one,
    if any file includes localtimer.h without CONFIG_LOCAL_TIMERS defined.
    
      arch/arm/include/asm/localtimer.h: In function ‘local_timer_setup’:
      arch/arm/include/asm/localtimer.h:53:10: error: ‘ENXIO’ undeclared (first use in this function)
