genirq: Adjust irq thread affinity on IRQ_SET_MASK_OK_NOCOPY return value

2012-04-13T15:14:06Z

commit f5cb92ac82d06cb583c1f66666314c5c0a4d7913 upstream. irq_move_masked_irq() checks the return code of chip->irq_set_affinity() only for 0, but IRQ_SET_MASK_OK_NOCOPY is also a valid return code, which is there to avoid a redundant copy of the cpumask. But in case of IRQ_SET_MASK_OK_NOCOPY we not only avoid the redundant copy, we also fail to adjust the thread affinity of an eventually threaded interrupt handler. Handle IRQ_SET_MASK_OK (==0) and IRQ_SET_MASK_OK_NOCOPY(==1) return values correctly by checking the valid return values seperately.

genirq: Move INPROGRESS, MASKED and DISABLED state flags to irq_data

2011-03-28T14:55:10Z

We really need these flags for some of the interrupt chips. Move it from internal state to irq_data and provide proper accessors. Signed-off-by: Thomas Gleixner Cc: David Daney

genirq: Implement irq_data based move_*_irq() versions

No need to lookup the irq descriptor when calling from a chip callback function which has irq_data already handy. Signed-off-by: Thomas Gleixner

genirq: Mirror IRQ_PER_CPU and IRQ_NO_BALANCING in irq_data.state

2011-02-19T11:58:20Z

That's the right data structure to look at for arch code. Accessor functions are provided. irqd_is_per_cpu(irqdata); irqd_can_balance(irqdata); Coders who access them directly will be tracked down and slapped with stinking trouts. Signed-off-by: Thomas Gleixner
