-Subject: [PATCH] MIPS: Lantiq: Fix cascaded IRQ setup
-
-With the IRQ stack changes integrated, the XRX200 devices started
-emitting a constant stream of kernel messages like this:
-
-[  565.415310] Spurious IRQ: CAUSE=0x1100c300
-
-This appears to be caused by IP0 firing for some reason without being
-handled. Fix this by setting up IP2-6 as a proper chained IRQ handler and
-calling do_IRQ for all MIPS CPU interrupts.
