Hi, While working on the SiS85C497 PIRQ router I have noticed an odd phenomenon with my venerable Tyan Tomcat IV S1564D board, where the PCI INTD# line of the USB host controller included as function 3 of the PIIX3 southbridge cannot be routed in the `noapic' mode. As it turns out the reason for this is the BIOS has two individual entries in its PIRQ table for two of its three functions, and the wrong one is chosen for routing said line. Strictly speaking this violates the PCI BIOS specification, but it can be easily worked around while preserving the semantics for compliant systems. Therefore I have come up with this patch series, which addresses this problem with 3/3, adds function reporting to the debug PIRQ table dump with 2/3 and also prints a usable physical memory address of the PIRQ table in a debug message with 1/3. See individual change descriptions for further details. Please apply. Maciej
