The PCI IRQs were regressing due to two things: - The PCI glue layer was using an hard-coded IRQ 27 offset. This caused the immediate regression. - The SIC IRQ mask was inverted (i.e. a bit was indeed set to one for each valid IRQ on the SIC, but accidentally inverted in the init call). This has been around forever, but we have been saved by some other forgiving code that would reserve IRQ descriptors in this range, as the versatile is non-sparse. When the IRQs were bumped up 32 steps so as to avoid using IRQ zero and avoid touching the 16 legacy IRQs, things broke. Introduce an explicit valid mask for the IRQs that are active on the PIC/SIC, and pass that. Use the BIT() macro from <linux/bitops.h> to make sure we hit the right bits, readily defined in <mach/platform.h>.
