Subject: PME and dependency on ACPI

I think that PME may place an unnecessary dependency on ACPI...

in drivers/pci/pcie/Kconfig:

config PCIE_PME
	def_bool y
	depends on PCIEPORTBUS && PM_RUNTIME && ACPI


and drivers/pci/pcie/pme.c:

#include <linux/acpi.h>
#include <linux/pci-acpi.h>

On an ARM platform I can remove the #include's and remove the Kconfig
dependency on ACPI and PME springs into life. 

Is there any other reason why ACPI may be needed here?
