Merge tag 'pci-v3.12-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI changes from Bjorn Helgaas: PCI device hotplug: - Use PCIe native hotplug, not ACPI hotplug, when possible (Neil Horman) - Assign resources on per-host bridge basis (Yinghai Lu) MPS (Max Payload Size): - Allow larger MPS settings below hotplug-capable Root Port (Yijing Wang) - Add warnings about unsafe MPS settings (Yijing Wang) - Simplify interface and messages (Bjorn Helgaas) SR-IOV: - Return -ENOSYS on non-SR-IOV devices (Stefan Assmann) - Update NumVFs register when disabling SR-IOV (Yijing Wang) Virtualization: - Add bus and slot reset support (Alex Williamson) - Fix ACS (Access Control Services) issues (Alex Williamson) Miscellaneous: - Simplify PCIe Capability accessors (Bjorn Helgaas) - Add pcibios_pm_ops for arch-specific hibernate stuff (Sebastian Ott) - Disable decoding during BAR sizing only when necessary (Zoltan Kiss) - Delay enabling bridges until they're needed (Yinghai Lu) - Split Designware support into Synopsys and Exynos parts (Jingoo Han) - Convert class code to use dev_groups (Greg Kroah-Hartman) - Cleanup Designware and Exynos I/O access wrappers (Seungwon Jeon) - Fix bridge I/O window alignment (Bjorn Helgaas) - Add pci_wait_for_pending_transaction() (Casey Leedom) - Use devm_ioremap_resource() in Marvell driver (Tushar Behera) * tag 'pci-v3.12-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: (63 commits) PCI/ACPI: Fix _OSC ordering to allow PCIe hotplug use when available PCI: exynos: Add I/O access wrappers PCI: designware: Drop "addr" arg from dw_pcie_readl_rc()/dw_pcie_writel_rc() PCI: Remove pcie_cap_has_devctl() PCI: Support PCIe Capability Slot registers only for ports with slots PCI: Remove PCIe Capability version checks PCI: Allow PCIe Capability link-related register access for switches PCI: Add offsets of PCIe capability registers PCI: Tidy bitmasks and spacing of PCIe capability definitions PCI: Remove obsolete comment reference to pci_pcie_cap2() PCI: Clarify PCI_EXP_TYPE_PCI_BRIDGE comment PCI: Rename PCIe capability definitions to follow convention PCI: Warn if unsafe MPS settings detected PCI: Fix MPS peer-to-peer DMA comment syntax PCI: Disable decoding for BAR sizing only when it was actually enabled PCI: Add comment about needing pci_msi_off() even when CONFIG_PCI_MSI=n PCI: Add pcibios_pm_ops for optional arch-specific hibernate functionality PCI: Don't restrict MPS for slots below Root Ports PCI: Simplify MPS test for Downstream Port PCI: Remove unnecessary check for pcie_get_mps() failure ...
