The patch adds boundary check for the MAX_GSI_NUM. Same as the update for
i386, the patch addresses a problem with ACPI SCI IRQ. The patch corrects
the code such that SCI IRQ is skipped and duplicate entry is avoided. The
VIA chipset uses 4-bit IRQ register for internal interrupt routing, and
therefore cannot handle IRQ numbers assigned to its devices. The patch
corrects this problem by allowing PCI IRQs below 16.
