Interrupts specified through an "Interrupt" ACPI resource (versus through a "GpioInt" resource) are now always assumed to be active low. When this change was originally made the Thinkpad 8 quirk was kept around because it was uncertain if the Thinkpad 8 uses an "Interrupt" or a "GpioInt" resource. Bug https://bugzilla.kernel.org/show_bug.cgi?id=196701 has a DSDT for the Thinkpad 8 attached and it uses an "Interrupt" resource, so the quirk is not necessary and the quirk, as well as the irq-active-low quirk handling code can be removed.
