Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Squash portdrv_{core,pci}.c into portdrv.c to ease maintenance and
     make more things static.

   - Make portdrv bind to Switch Ports that have AER. Previously, if
     these Ports lacked MSI/MSI-X, portdrv failed to bind, which meant
     the Ports couldn't be suspended to low-power states. AER on these
     Ports doesn't use interrupts, and the AER driver doesn't need to
     claim them.

   - Assign PCI domain IDs using ida_alloc(), which makes host bridge
     add/remove work better.

  Resource management:

   - To work better with recent BIOSes that use EfiMemoryMappedIO for
     PCI host bridge apertures, remove those regions from the E820 map
     (E820 entries normally prevent us from allocating BARs). In v5.19,
     we added some quirks to disable E820 checking, but that's not very
     maintainable. EfiMemoryMappedIO means the OS needs to map the
     region for use by EFI runtime services; it shouldn't prevent OS
     from using it.

  PCIe native device hotplug:

   - Build pciehp by default if USB4 is enabled, since Thunderbolt/USB4
     PCIe tunneling depends on native PCIe hotplug.

   - Enable Command Completed Interrupt only if supported to avoid user
     confusion from lspci output that says this is enabled but not
     supported.

   - Prevent pciehp from binding to Switch Upstream Ports; this happened
     because of interaction with acpiphp and caused devices below the
     Upstream Port to disappear.

  Power management:

   - Convert AGP drivers to generic power management. We hope to remove
     legacy power management from the PCI core eventually.

  Virtualization:

   - Fix pci_device_is_present(), which previously always returned
     "false" for VFs, causing virtio hangs when unbinding the driver.

  Miscellaneous:

   - Convert drivers to gpiod API to prepare for dropping some legacy
     code.

   - Fix DOE fencepost error for the maximum data object length.

  Baikal-T1 PCIe controller driver:

   - Add driver and DT bindings.

  Broadcom STB PCIe controller driver:

   - Enable Multi-MSI.

   - Delay 100ms after PERST# deassert to allow power and clocks to
     stabilize.

   - Configure Read Completion Boundary to 64 bytes.

  Freescale i.MX6 PCIe controller driver:

   - Initialize PHY before deasserting core reset to fix a regression in
     v6.0 on boards where the PHY provides the reference.

   - Fix imx6sx and imx8mq clock names in DT schema.

  Intel VMD host bridge driver:

   - Fix Secondary Bus Reset on VMD bridges, which allows reset of NVMe
     SSDs in VT-d pass-through scenarios.

   - Disable MSI remapping, which gets re-enabled by firmware during
     suspend/resume.

  MediaTek PCIe Gen3 controller driver:

   - Add MT7986 and MT8195 support.

  Qualcomm PCIe controller driver:

   - Add SC8280XP/SA8540P basic interconnect support.

  Rockchip DesignWare PCIe controller driver:

   - Base DT schema on common Synopsys schema.

  Synopsys DesignWare PCIe core:

   - Collect DT items shared between Root Port and Endpoint (PERST GPIO,
     PHY info, clocks, resets, link speed, number of lanes, number of
     iATU windows, interrupt info, etc) to snps,dw-pcie-common.yaml.

   - Add dma-ranges support for Root Ports and Endpoints.

   - Consolidate DT resource retrieval for "dbi", "dbi2", "atu", etc. to
     reduce code duplication.

   - Add generic names for clocks and resets to encourage more
     consistent naming across drivers using DesignWare IP.

   - Stop advertising PTM Responder role for Endpoints, which aren't
     allowed to be responders.

  TI J721E PCIe driver:

   - Add j721s2 host mode ID to DT schema.

   - Add interrupt properties to DT schema.

  Toshiba Visconti PCIe controller driver:

   - Fix interrupts array max constraints in DT schema"

Pull iommufd implementation from Jason Gunthorpe:
 "iommufd is the user API to control the IOMMU subsystem as it relates
  to managing IO page tables that point at user space memory.

  It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO
  container) which is the VFIO specific interface for a similar idea.

  We see a broad need for extended features, some being highly IOMMU
  device specific:
   - Binding iommu_domain's to PASID/SSID
   - Userspace IO page tables, for ARM, x86 and S390
   - Kernel bypassed invalidation of user page tables
   - Re-use of the KVM page table in the IOMMU
   - Dirty page tracking in the IOMMU
   - Runtime Increase/Decrease of IOPTE size
   - PRI support with faults resolved in userspace

  Many of these HW features exist to support VM use cases - for instance
  the combination of PASID, PRI and Userspace IO Page Tables allows an
  implementation of DMA Shared Virtual Addressing (vSVA) within a guest.
  Dirty tracking enables VM live migration with SRIOV devices and PASID
  support allow creating "scalable IOV" devices, among other things.

  As these features are fundamental to a VM platform they need to be
  uniformly exposed to all the driver families that do DMA into VMs,
  which is currently VFIO and VDPA"

   enabled during per-cpu page allocations
