Two storage classes issues and a dereferencing a 'noderef' pointer. These are the warnings: arch/powerpc/xmon/xmon.c:2783:1: warning: symbol 'dump_log_buf' was not declared. Should it be static? arch/powerpc/xmon/xmon.c:2989:6: warning: symbol 'format_pte' was not declared. Should it be static? arch/powerpc/xmon/xmon.c:2983:30: warning: dereference of noderef expression This patch fixes all of them, turning both functions static and dereferencing a pointer calling rcu_dereference() instead of a straightforward dereference.
