This series is based Bjorn's pci-next branch + Alexander Gordeev's two patches "Remove arch_msi_check_device()" link: https://lkml.org/lkml/2014/7/12/41 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. It has been tested fine in x86(with or without irq remap). 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.
