genirq: Introduce irq_do_set_affinity() to reduce duplicated code

2012-05-24T20:36:40+00:00

All invocations of chip->irq_set_affinity() are doing the same return
value checks. Let them all use a common function.

[ tglx: removed the silly likely while at it ]

genirq: Adjust irq thread affinity on IRQ_SET_MASK_OK_NOCOPY return value

2012-03-30T21:13:46+00:00

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

2011-03-28T14:55:10+00:00

We really need these flags for some of the interrupt chips. Move it
from internal state to irq_data and provide proper accessors.

genirq: Implement irq_data based move_*_irq() versions

2011-02-19T11:58:25+00:00

No need to lookup the irq descriptor when calling from a chip callback
function which has irq_data already handy.

genirq: Mirror IRQ_PER_CPU and IRQ_NO_BALANCING in irq_data.state

2011-02-19T11:58:20+00:00

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.

2011-02-19T11:58:18+00:00

chip implementations need to know about it. Keep status in sync until
all users are fixed. 

Accessor function: irqd_is_setaffinity_pending(irqdata)

Coders who access them directly will be tracked down and slapped with
stinking trouts.
