Thanks for looking at the patch.

I guess you mean that ACPI should hide all this behind an irq_chip
abstraction. I had a quick look at doing this but not being very
familiar with ACPI nor irq_chip I don't think I'm the right person for
the task. Hopefully it is not seen as a merge requirement...

CCing ACPI list for comments.
