Merge branch 'pci/edr'
- Update error status after reset_link() so we don't report "recovery failed" when it in fact succeeded (Kuppuswamy Sathyanarayanan) - Move DPC data into struct pci_dev instead of allocating a separate struct dpc_dev (Bjorn Helgaas) - Remove AER/DPC service dependency to simplify error recovery (Kuppuswamy Sathyanarayanan) - Return error recovery status for future use by EDR, which needs to tell firmware whether recovery was successful (Kuppuswamy Sathyanarayanan) - Cache DPC capability info in core since it's needed by EDR as well as DPC driver (Kuppuswamy Sathyanarayanan) - Add pci_aer_raw_clear_status() to allow EDR recovery path to clear AER status even when OS doesn't own the AER capability (Kuppuswamy Sathyanarayanan) - Add Error Disconnect Recover (EDR) support, so firmware can use ACPI notification to tell the OS that devices have been disconnected, e.g., via DPC, and that OS should attempt recovery (Kuppuswamy Sathyanarayanan) - Rename AER error status clearing interfaces to be more consistent (Kuppuswamy Sathyanarayanan) * pci/edr: PCI/AER: Rationalize error status register clearing PCI/DPC: Add Error Disconnect Recover (EDR) support PCI/DPC: Expose dpc_process_error(), dpc_reset_link() for use by EDR PCI/AER: Add pci_aer_raw_clear_status() to unconditionally clear Error Status PCI/DPC: Cache DPC capabilities in pci_init_capabilities() PCI/ERR: Return status of pcie_do_recovery() PCI/ERR: Remove service dependency in pcie_do_recovery() PCI/DPC: Move DPC data into struct pci_dev PCI/ERR: Update error status after reset_link() PCI/ERR: Combine pci_channel_io_frozen cases
