Currently sparse is complaining about three issues on the xmon code. 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.
