Yifeng Li 5f5f67da97 mips: loongson64: lemote-2f: Add IRQF_NO_SUSPEND to "cascade" irqaction. ... Timekeeping IRQs from CS5536 MFGPT are routed to i8259, which then triggers the "cascade" IRQ on MIPS CPU. Without IRQF_NO_SUSPEND in cascade_irqaction, MFGPT interrupts will be masked in suspend mode, and the machine would be unable to resume once suspended. Previously, MIPS IRQs were not disabled properly, so the original code appeared to work. Commit a3e6c1eff5 ("MIPS: IRQ: Fix disable_irq on CPU IRQs") uncovers the bug. To fix it, add IRQF_NO_SUSPEND to cascade_irqaction. This commit is functionally identical to 0add9c2f1c ("MIPS: Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction"), but it forgot to apply the same fix to Loongson2.
