Subject[PATCH][2.4.26 x86_64] fix ACPI PRT entry handling
Date
From

This patch fixes a PCI interrupt routing bug that shows up when running
on x86_64 with ACPI and IOAPIC functionality enabled. Without this patch
in place, the code attempts to route all configurable PCI interrupts to
IRQ 0.

Regards

Andy
