[PATCH] MIPS: export get_c0_perfcount_int()

[PATCH] MIPS: export get_c0_perfcount_int()

[Felix Fietkau]

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")

You didn't actually cc this email to stable@vger.kernel.org.

Pistachio was merged for 4.1 so this patch won't apply to older kernels.
You may also want to submit a separate version for those -stable kernels.

Applied.
