From: Doug Meyer <dmeyer@xxxxxxxxxx> This is a resend of the patch series to enable Microsemi Switchtec NTB configurations to run 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. Blessings, Doug Meyer Changes since v1: - Call pci_device_disable() at return points to clean up properly. - Changed all dev_* print macros to pci_* macros. - Removed superfluous variable initializations.
