-Subject: [PATCH 87/91] net-next: mediatek: add IRQ locking
-
-The code that enables and disables IRQs is missing proper locking. After
-adding the IRQ separation patch and routing the putting the RX and TX IRQs
-on different cores we experienced IRQ stalls. Fix this by adding proper
-locking. We use a dedicated lock to reduce the latency if the IRQ code.
-Otherwise it might wait for bottom code to finish before reenabling or
-disabling IRQs.
