From: Doug Meyer <dmeyer@xxxxxxxxxx> This patch series addresses the need to be able to run Microsemi Switchtec NTB configurations with the IOMMU in the hosts turned on. Because of the nature PCI Quirk implementation, it was preferable to migrate the Microsemi PCI vendor and device definitions to the Linux canonical location. Logan Gunthorpe requested that this migration be done as a separate patch in a set, and so this patch series was created as shown here. The first patch encapsulates the movement of constants from switchtec.h to pci_ids.h, with commensurate changes to the source files. This patch is not dependent on any other work. The second patch is the PCI quirk implementation itself, and is completely dependent upon the first patch in this series. Testing of the quirk was done on with a 2-host x86-64 system with all combinations of IOMMU off/on. The ntb_perf module was used as test stimulus.
