Revision 52abb700e16a9aa4cbc03f3d7f80206cbbc80680 authored by Thomas Gleixner on 06 March 2012, 22:18:54 UTC, committed by Linus Torvalds on 07 March 2012, 00:46:39 UTC
Xommit 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.
