This series is based Bjorn's pci/msi branch git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git pci/msi Currently, there are a lot of weak arch functions in MSI code. Thierry Reding Introduced MSI chip framework to configure MSI/MSI-X in arm. This series use MSI chip framework to refactor MSI code across all platforms to eliminate weak arch functions. Then all MSI irqs will be managed in a unified framework. Because this series changed a lot of ARCH MSI code, so tests in the platforms which MSI code modified are warmly welcomed! v1->v2: Add a patch to make s390 MSI code build happy between patch "x86/xen/MSI: E.." and "s390/MSI: Use MSI..". Fix several typo problems found by Lucas. RFC->v1: Updated "[patch 4/21] x86/xen/MSI: Eliminate...", export msi_chip instead of #ifdef to fix MSI bug in xen running in x86. Rename arch_get_match_msi_chip() to arch_find_msi_chip(). Drop use struct device as the msi_chip argument, we will do that later in another patchset.
