MIPS: Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction
[ Upstream commit 0add9c2f1cff9f3f1f2eb7e9babefa872a9d14b9 ]
HPET irq is routed to i8259 and then to MIPS CPU irq (cascade). After
commit a3e6c1eff5 (MIPS: IRQ: Fix disable_irq on CPU IRQs), if without
IRQF_NO_SUSPEND in cascade_irqaction, HPET interrupts will lost during
suspend. The result is machine cannot be waken up.
