* pci/aer:
  PCI/AER: Support ACPI HEST AER error sources for PCI domains other than 0
  ACPICA: Add helper macros to extract bus/segment numbers from HEST table.

In the discussion for this set of patches [link below], Bjorn Helgaas
pointed out that the ACPI HEST AER error sources do not have the PCIe
segment number associated with the bus.  I worked with the ACPI spec and
got this change to definition of the "Bus" field into the recently released
ACPI Spec 5.0a section 18.3.2.3-5:

  Identifies the PCI Bus and Segment of the device.  The Bus is encoded in
  bits 0-7.  For systems that expose multiple PCI segment groups, the
  segment number is encoded in bits 8-23 and bits 24-31 must be zero.  For
  systems that do not expose multiple PCI segment groups, bits 8-31 must be
  zero.  If the GLOBAL flag is specified, this field is ignored.

This patch makes use of the new definition in the only place in the kernel
that uses the acpi_hest_aer_common's bus field.

This depends on 36f3615152c1 ("ACPICA: Add helper macros to extract
bus/segment numbers from HEST table.")

My philosophy is unused code is dead code.  And dead code is subject to bit
rot and is a likely source of bugs.  Use it or lose it.

This reverts part of 3e1b16002af2 ("ACPI/PCI: PCIe ASPM _OSC support
capabilities called when root bridge added"), removing this interface:

    pcie_aspm_enabled()

* pci/msi:
  PCI/MSI: Add pci_enable_msi_range() and pci_enable_msix_range()
  PCI/MSI: Add pci_msix_vec_count()
  PCI/MSI: Remove pci_enable_msi_block_auto()
  PCI/MSI: Add pci_msi_vec_count()

This creates an MSI-X counterpart for pci_msi_vec_count().  Device drivers
can use this function to obtain maximum number of MSI-X interrupts the
device supports and use that number in a subsequent call to
pci_enable_msix().

pci_msix_vec_count() supersedes pci_msix_table_size() and returns a
negative errno if device does not support MSI-X interrupts.  After this
update, callers must always check the returned value.

The only user of pci_msix_table_size() was the PCI-Express port driver,
which is also updated by this change.

* pci/deletion:
  PCI/portdrv: Remove extra get_device()/put_device() for pcie_device
  PCI/portdrv: Add put_device() after device_register() failure
  PCI/portdrv: Cleanup error paths

Previously pcie_device_init() called get_device() if device_register() for
the new pcie_device succeeded, and remove_iter() called put_device() when
removing before unregistering the device.

But device_register() already increments the reference count in
device_add(), so we don't need to do it again here.

This is required so that we give up the last reference to the device.
Removed the kfree() as put_device will result in release_pcie_device()
being called and hence the container of the device will be kfree'd.

Make the straightline path the normal no-error path.  Check for errors and
return them directly, instead of checking for success and putting the
normal path in an "if" body.

No functional change.
