This series attempts to align as much IRQ handling into the probe path as possible. Note that I don't have a great setup for testing these patches so they are mostly just build tested and need careful review and testing before any of them are merged.
The series brings the ACPI path inline with the way the device tree path handles the IRQ entirely at probe time. However, it still leaves any IRQ specified through the board_info as being handled at device time. In that case we need to cache something from the board_info until probe time, which leaves any alternative solution with something basically the same as the current handling although perhaps caching more stuff.
