This patch breaks module build of mvneta unless you export request_percpu_irq :

diff --git a/kernel/irq/manage.c b/kernel/irq/manage.c
index ec31697..1440a92 100644
--- a/kernel/irq/manage.c
+++ b/kernel/irq/manage.c
@@ -1799,6 +1799,7 @@ int request_percpu_irq(unsigned int irq, irq_handler_t handler,

return retval;
}
+EXPORT_SYMBOL_GPL(request_percpu_irq);

Regards,
Willy
