[RFC PATCH] set current_state to D0 in register_slot
...ore the device" */
at this point if we refer to the commit message that introduced the
comment above (10b3dcae0f275e2546e55303d64ddbb58cec7599), it is up to
the hotplug driver to set the state to D0.
However AFAICT the pci hotplug driver never does, in fact
drivers/pci/hotplug/acpiphp_glue.c:register_slot sets the slot flags to
(SLOT_ENABLED | SLOT_POWEREDON) but it does not set the pci device
current state to PCI_D0.
So my proposed fix is also to set current_state = PCI_D0 in
register_slot.
Comments are very welcome.

[PATCH] tools/firmware: remove "_PS0/3" Method
tools/firmware: remove "_PS0/3" Method
Do not expose the ACPI power management "_PS0/3" Method to guest firmware. According to section 3.4 of the APCI specification 4.0, PCI device control the device power through its own specification but not through APCI.
Qemu pushes "_PS0/3" to guest will cause a mess between ACPI PM and PCI PM as a result of incorrect ACPI table
