Merge branch 'pci/aer'

- Allow drivers to request a Bus Reset on Non-Fatal Errors (Lukas Wunner)

- Send uevents for subordinate devices (not the bridge) on failure to
  recover from errors on the subordinate devices (Lukas Wunner)

- Notify drivers by calling their err_handler.error_detected() callback on
  failure to recover (Lukas Wunner)

- Update device error_state earlier after reset to align AER and EEH error
  recovery (Lukas Wunner)

- Remove obsolete comments about .link_reset(), which was removed long ago
  (Lukas Wunner)

- Emit a uevent for the beginning of error recovery if driver requests a
  reset (Niklas Schnelle)

- Emit error recover uevents on s390 as is done by EEH and AER (Niklas
  Schnelle)

- Include error_detected() result in AER uevent to align with corresponding
  uevents from EEH and s390 (Niklas Schnelle)

- Decode new errors added in PCIe r6.0 (Lukas Wunner)

- Print TLP Log for errors introduced since PCIe spec r1.1 (Lukas Wunner)

- Check for allocation failure in pci_aer_init() (Vernon Yang)

- Update error recovery documentation to match the current code and use
  consistent nomenclature (Lukas Wunner)

- Avoid NULL pointer dereference in aer_ratelimit() when GHES error info
  points to a device with no AER Capability (Breno Leitao)
