Subject: [PATCH v12 0/5] Simplify PCIe native ownership

From: Bjorn Helgaas <bhelgaas@...gle.com>

This is Sathy's work with a few tweaks on top.

I dropped the DPC pcie_ports_dpc_native changes for now just because I
haven't had time to understand it all.  We currently ignore the
OSC_PCI_EXPRESS_DPC_CONTROL bit, which seems wrong.  We might want to start
looking at it, but we should try to make that a separate patch that's as
small as possible.

Changes since v11:
 * Add bugfix for DPC with no AER Capability
 * Split OSC_OWNER trivial changes from pcie_ports_native changes
 * Temporarily drop pcie_ports_dpc_native changes
