Subject: [PATCH 3.19.y-ckt 034/102] MIPS: Export get_c0_perfcount_int()

3.19.8-ckt7 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felix Fietkau <nbd@...nwrt.org>

commit 0cb0985f57783c2f3c6c8ffe7e7665e80c56bd92 upstream.

get_c0_perfcount_int is tested from oprofile code. If oprofile is
compiled as module, get_c0_perfcount_int needs to be exported, otherwise
it cannot be resolved.

Fixes: a669efc4a3b4 ("MIPS: Add hook to get C0 performance counter interrupt")
