[PATCH v2] arc: kernel: use exporting symbol instead of static inlinefor arc_get_core_freq()

From: Chen Gang
Date: Mon Oct 28 2013 - 02:19:32 EST


Need export arc_get_core_freq() instead of let it static inline, or if
other individual modules use it (e.g. use BASE_BAUD), it can not find
core_freq variable.
