Merge tag 'pci-v3.17-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas: "I'll be on vacation until Aug 11, and I suspect the merge window will open before then, so I'm sending this to you early. There are more things I'd like to get into v3.17, so I hope to send another pull request soon after I return. The most notable pieces here are: - Support BARs up to 128GB (up from 8GB) - Fix SR-IOV resource assignment when we fail to expand a resource - Rework pciehp to handle a common hardware erratum - Cleanup MSI - Fix NIC renaming issue - Fix VGA default device issue on EFI systems - Fix ASPM configuration (previously we didn't enable it as expected) Alex Williamson has graciously agreed to take care of any major issues with this if you take it before I return. Details: Resource management - Support BAR sizes up to 128GB (Yinghai Lu) - Keep original resource if we fail to expand it (Guo Chao) - Return conventional error values from pci_revert_fw_address() (Bjorn Helgaas) - Tidy resource assignment messages (Bjorn Helgaas) - Don't exclude low BIOS area for non-PCI cards (Christoph Schulz) PCI device hotplug - Prevent NULL dereference during pciehp probe (Andreas Noever) - Make pciehp pcie_wait_cmd() self-contained (Bjorn Helgaas) - Wait for pciehp hotplug command completion lazily (Bjorn Helgaas) - Compute pciehp timeout from hotplug command start time (Bjorn Helgaas) - Remove pciehp assumptions about which commands cause completion events (Bjorn Helgaas) - Clear pciehp Data Link Layer State Changed during init (Myron Stowe) - Remove pciehp struct controller.no_cmd_complete (Rajat Jain) - Remove cpqphp unnecessary null test (Fabian Frederick) - Remove "invalid IRQ" warning for hot-added PCIe ports (Jiang Liu) IOMMU - Add DMA alias quirk for Intel 82801 bridge (Alex Williamson) MSI - Add internal msix_clear_and_set_ctrl() (Yijing Wang) - Remove unused msi_enabled_mask() (Yijing Wang) - Cache Multiple Message Capable in struct msi_desc (Yijing Wang) - Add msi_setup_entry() to clean up initialization (Yijing Wang) - Remove unused msi_remove_pci_irq_vectors() (Yijing Wang) - Retrieve first MSI IRQ from msi_desc rather than pci_dev (Yijing Wang) - Remove unused list access in __pci_restore_msix_state() (Yijing Wang) - Use irq_get_msi_desc() to simplify code (Yijing Wang) Generic host bridge driver - Fix GPL v2 license string typo (Bjorn Helgaas) Marvell MVEBU - Fix GPL v2 license string typo (Thierry Reding) NVIDIA Tegra - Use correct initial HW settings (Phil Edworthy) - Remove rcar_pcie_setup_window() resource argument (Phil Edworthy) - Fix GPL v2 license string typo (Thierry Reding) Renesas R-Car - Remove redundant config accessor register checks (Sergei Shtylyov) - Fix GPL v2 license string typo (Bjorn Helgaas) Virtualization - Factor secondary bus reset logic (Gavin Shan) - Remove duplicate powerpc reset logic (Gavin Shan) Miscellaneous - Rework default VGA detection for EFI (Bruno Prémont) - Fix sysfs "acpi_index" and "label" errors for NIC renaming (Simone Gotti) - Configure ASPM at pci_enable_device()-time (Vidya Sagar) - Add include/linux/pci_ids.h include guard (Rasmus Villemoes)" * tag 'pci-v3.17-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: (38 commits) PCI/MSI: Use irq_get_msi_desc() to simplify code PCI/MSI: Remove unused list access in __pci_restore_msix_state() PCI/MSI: Retrieve first MSI IRQ from msi_desc rather than pci_dev PCI/MSI: Remove unused function msi_remove_pci_irq_vectors() PCI/MSI: Add msi_setup_entry() to clean up MSI initialization PCI: Configure ASPM when enabling device x86: don't exclude low BIOS area when allocating address space for non-PCI cards PCI: generic: Fix GPL v2 license string typo PCI: rcar: Fix GPL v2 license string typo PCI: tegra: Fix GPL v2 license string typo PCI: mvebu: Fix GPL v2 license string typo PCI: Add include guard to include/linux/pci_ids.h x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup() PCI: Tidy resource assignment messages PCI: Return conventional error values from pci_revert_fw_address() PCI: Cleanup control flow PCI: Support BAR sizes up to 128GB PCI: cpqphp: Remove unnecessary null test before debugfs_remove() PCI: pciehp: Clear Data Link Layer State Changed during init PCI: Add bridge DMA alias quirk for Intel 82801 bridge ...
