Merge tag 'pci-v3.10-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas: "PCI changes for the v3.10 merge window: PCI device hotplug - Remove ACPI PCI subdrivers (Jiang Liu, Myron Stowe) - Make acpiphp builtin only, not modular (Jiang Liu) - Add acpiphp mutual exclusion (Jiang Liu) Power management - Skip "PME enabled/disabled" messages when not supported (Rafael Wysocki) - Fix fallback to PCI_D0 (Rafael Wysocki) Miscellaneous - Factor quirk_io_region (Yinghai Lu) - Cache MSI capability offsets & cleanup (Gavin Shan, Bjorn Helgaas) - Clean up EISA resource initialization and logging (Bjorn Helgaas) - Fix prototype warnings (Andy Shevchenko, Bjorn Helgaas) - MIPS: Initialize of_node before scanning bus (Gabor Juhos) - Fix pcibios_get_phb_of_node() declaration "weak" annotation (Gabor Juhos) - Add MSI INTX_DISABLE quirks for AR8161/AR8162/etc (Xiong Huang) - Fix aer_inject return values (Prarit Bhargava) - Remove PME/ACPI dependency (Andrew Murray) - Use shared PCI_BUS_NUM() and PCI_DEVID() (Shuah Khan)" * tag 'pci-v3.10-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: (63 commits) vfio-pci: Use cached MSI/MSI-X capabilities vfio-pci: Use PCI_MSIX_TABLE_BIR, not PCI_MSIX_FLAGS_BIRMASK PCI: Remove "extern" from function declarations PCI: Use PCI_MSIX_TABLE_BIR, not PCI_MSIX_FLAGS_BIRMASK PCI: Drop msi_mask_reg() and remove drivers/pci/msi.h PCI: Use msix_table_size() directly, drop multi_msix_capable() PCI: Drop msix_table_offset_reg() and msix_pba_offset_reg() macros PCI: Drop is_64bit_address() and is_mask_bit_support() macros PCI: Drop msi_data_reg() macro PCI: Drop msi_lower_address_reg() and msi_upper_address_reg() macros PCI: Drop msi_control_reg() macro and use PCI_MSI_FLAGS directly PCI: Use cached MSI/MSI-X offsets from dev, not from msi_desc PCI: Clean up MSI/MSI-X capability #defines PCI: Use cached MSI-X cap while enabling MSI-X PCI: Use cached MSI cap while enabling MSI interrupts PCI: Remove MSI/MSI-X cap check in pci_msi_check_device() PCI: Cache MSI/MSI-X capability offsets in struct pci_dev PCI: Use u8, not int, for PM capability offset [SCSI] megaraid_sas: Use correct #define for MSI-X capability PCI: Remove "extern" from function declarations ...
