I posted a follow up patch a minute ago. 

[PATCH 1/3] Revert "ACPI,PCI,IRQ: reduce static IRQ array size to 16"
[PATCH 2/3] ACPI, PCI IRQ: add PCI_USING penalty for ISA interrupts
[PATCH 3/3] Revert "ACPI,PCI,IRQ: remove SCI penalize function"

Can we have some testing coverage? and eventually have tested-by?
