Merge branch 'pci/gavin-msi-cleanup' into next
* pci/gavin-msi-cleanup:
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
