The pcie_ports parameter, which defaults to 'auto', allows a user to specify if PCIe port services are disabled ('compat'), always enabled ('native'), or only used when allowed by the BIOS ('auto'). Where CONFIG_ACPI isn't enabled, as is often the case for non x86/ia64 platforms, the 'auto' behavior results in that of 'compat'. Thus in order to use port services on these platforms 'pcie_ports=native' must be added to the kernel command line. This patch results in the 'native' behavior being followed where 'auto' is selected and ACPI is not enabled.
