* 'next-rebase' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci:
PCI: Clean-up MPS debug output
pci: Clamp pcie_set_readrq() when using "performance" settings
PCI: enable MPS "performance" setting to properly handle bridge MPS
PCI: Workaround for Intel MPS errata
PCI: Add support for PASID capability
PCI: Add implementation for PRI capability
PCI: Export ATS functions to modules
PCI: Move ATS implementation into own file
PCI / PM: Remove unnecessary error variable from acpi_dev_run_wake()
PCI hotplug: acpiphp: Prevent deadlock on PCI-to-PCI bridge remove
PCI / PM: Extend PME polling to all PCI devices
PCI quirk: mmc: Always check for lower base frequency quirk for Ricoh 1180:e823
PCI: Make pci_setup_bridge() non-static for use by arch code
x86: constify PCI raw ops structures
PCI: Add quirk for known incorrect MPSS
PCI: Add Solarflare vendor ID and SFC4000 device IDs
