This is a note to let you know that I have just added a patch titled MIPS: Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt11. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 10cef6c8a7ec323b97757590c2928d99c60c9626 Mon Sep 17 00:00:00 2001 From: Huacai Chen <chenhc@lemote.com> Date: Thu, 12 Mar 2015 11:51:06 +0800 Subject: MIPS: Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction 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.
