   3 Subject: [PATCH] MIPS: export get_c0_perfcount_int()
   4
   5 get_c0_perfcount_int is tested from oprofile code. If oprofile is
   6 compiled as module, get_c0_perfcount_int needs to be exported, otherwise
   7 it cannot be resolved.

   9 Fixes: a669efc4a3b4 ("MIPS: Add hook to get C0 performance counter interrupt")
  10 Cc: stable@vger.kernel.org # v3.19+
