We found these warnings in arch/powerpc/kernel/time.c as follows: warning: symbol 'decrementer_max' was not declared. Should it be static? warning: symbol 'rtc_lock' was not declared. Should it be static? warning: symbol 'dtl_consumer' was not declared. Should it be static?
Declare 'decrementer_max' in arch/powerpc/include/asm/time.h. And include proper header in which 'rtc_lock' is declared. Move 'dtl_consumer' definition behind "include <asm/dtl.h>" because 'dtl_consumer' is declared there.
