Hi Thomas,

Do you agree with the original patch concept: moving mask_cache from
struct irq_chip_generic into struct irq_chip_type ?

This allows to handle the irq_chips which have separate mask registers
for the edge and level interrupts. At the time of this patch, this was
the only existing case.

Saeed objected that the patch was not correct because this was breaking
"hypothetic" devices with multiple irq_chip_type and a single mask
register.

The other option was to provide some dedicated irq_mask handlers for the
Orion irq chip.

As I was comfortable with none of this solutions, I kind of let it lie.

Let me know you advice.

Simon
