skip AER driver error recovery callbacks for correctable errors reported via ACPI APEI, as we already do for errors reported via the native path (Tyler Baicar) - fix DPC shared interrupt handling (Alex Williamson) - print full DPC interrupt number (Keith Busch) - enable DPC only if AER is available (Keith Busch) - simplify DPC code (Bjorn Helgaas) - calculate ASPM L1 substate parameter instead of hardcoding it (Bjorn Helgaas) - enable Latency Tolerance Reporting for ASPM L1 substates (Bjorn Helgaas) - move ASPM internal interfaces out of public header (Bjorn Helgaas) - allow hot-removal of VGA devices (Mika Westerberg) - speed up unplug and shutdown by assuming Thunderbolt controllers don't support Command Completed events (Lukas Wunner) - add AtomicOps support for GPU and Infiniband drivers (Felix Kuehling, Jay Cornwall) - expose "ari_enabled" in sysfs to help NIC naming (Stuart Hayes) - clean up PCI DMA interface usage (Christoph Hellwig) - remove PCI pool API (replaced with DMA pool) (Romain Perier) - deprecate pci_get_bus_and_slot(), which assumed PCI domain 0 (Sinan Kaya) - move DT PCI code from drivers/of/ to drivers/pci/ (Rob Herring) - add PCI-specific wrappers for dev_info(), etc (Frederick Lawler) - remove warnings on sysfs mmap failure (Bjorn Helgaas) - quiet ROM validation messages (Alex Deucher) - remove redundant memory alloc failure messages (Markus Elfring) - fill in types for compile-time VGA and other I/O port resources (Bjorn Helgaas) - make "pci=pcie_scan_all" work for Root Ports as well as Downstream Ports to help AmigaOne X1000 (Bjorn Helgaas) - add SPDX tags to all PCI files (Bjorn Helgaas) - quirk Marvell 9128 DMA aliases (Alex Williamson) - quirk broken INTx disable on Ceton InfiniTV4 (Bjorn Helgaas) - fix CONFIG_PCI=n build by adding dummy pci_irqd_intx_xlate() (Niklas Cassel) - use DMA API to get MSI address for DesignWare IP (Niklas Cassel) -
