[PATCH v3 0/7] Fix issues and cleanup for ERR_FATAL and ERR_NONFATAL

[Bjorn Helgaas]

This is a v3 of Oza's patches [1].  It's available at [2] if you prefer
git.

v3 changes:
  - Add pci_aer_clear_fatal_status() to clear ERR_FATAL bits, only called
    from pcie_do_fatal_recovery().  Moved to first in series to avoid a
    window where ERR_FATAL recovery only clears ERR_NONFATAL bits.  Visible
    only inside the PCI core.
  - Instead of having pci_cleanup_aer_uncorrect_error_status() do different
    things based on dev->error_state, use this only for ERR_NONFATAL bits.
    I didn't change the name because it's used by many drivers.
  - Rename pci_cleanup_aer_error_device_status() to
    pci_aer_clear_device_status(), make it void, and make it visible only
    inside the PCI core.
  - Remove pcie_portdrv_err_handler.slot_reset altogether instead of making
    it a stub function.  Possibly pcie_portdrv_err_handler could be removed
    completely?
