+Subject: genirq: Clear action->thread_mask if IRQ_ONESHOT is not set
+
+commit ac5637611(genirq: Unmask oneshot irqs when thread was not woken)
+fails to unmask when a !IRQ_ONESHOT threaded handler is handled by
+handle_level_irq.
+
+This happens because thread_mask is or'ed unconditionally in
+irq_wake_thread(), but for !IRQ_ONESHOT interrupts never cleared. So
+the check for !desc->thread_active fails and keeps the interrupt
+disabled.
+
+Keep the thread_mask zero for !IRQ_ONESHOT interrupts.
+
+Document the thread_mask magic while at it.

+Subject: softirq: Check preemption after reenabling interrupts
+From: Thomas Gleixner <tglx at linutronix.de>
+Date: Sun, 13 Nov 2011 17:17:09 +0100 (CET)
+
+raise_softirq_irqoff() disables interrupts and wakes the softirq
+daemon, but after reenabling interrupts there is no preemption check,
+so the execution of the softirq thread might be delayed arbitrarily.
+
+In principle we could add that check to local_irq_enable/restore, but
+that's overkill as the rasie_softirq_irqoff() sections are the only
+ones which show this behaviour.
