From 68feac87de15edfc2c700d2d81b814288c93d003 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 16 Dec 2008 21:36:55 -0700 Subject: PCI: add pci_common_swizzle() for INTx swizzling This patch adds pci_common_swizzle(), which swizzles INTx values all the way up to a root bridge. This common implementation can replace several architecture-specific ones. This should someday be combined with pci_get_interrupt_pin(), but I left it separate for now to make reviewing easier.
