If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 0add9c2f1cff9f3f1f2eb7e9babefa872a9d14b9 Mon Sep 17 00:00:00 2001 From: Huacai Chen <chenhc@xxxxxxxxxx> Date: Thu, 12 Mar 2015 11:51:06 +0800 Subject: MIPS: Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction From: Huacai Chen <chenhc@xxxxxxxxxx> commit 0add9c2f1cff9f3f1f2eb7e9babefa872a9d14b9 upstream. 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.
