Since current_cpu is CPUState it no longer depends on CPUPPCState.

Move ppce500_set_mpic_proxy() to a new hw/ppc/ppc_e500.h because
hw/ppc/ppc.h is too heavily using CPUPPCState and PowerPCCPU.

pci: Use helper to find device's root bus in pci_find_domain()

Currently pci_find_domain() performs two functions - it locates the PCI
root bus above the given bus, then looks up that root bus's domain number.
This patch adds a helper function to perform the first task, finding the...

pci: Replace pci_find_domain() with more general pci_root_bus_path()

pci_find_domain() is used in a number of places where we want an id for a
whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is
that many platforms may support multiple independent host bridges with no...

pci: Add root bus argument to pci_get_bus_devfn()

pci_get_bus_devfn() interprets a full PCI address string to give a PCIBus *

pci: Add root bus parameter to pci_nic_init()

only create a NIC under the primary PCI root. As we add support for
multiple PCI roots, that may no longer be the case. This patch adds a root...

pci: Abolish pci_find_root_bus()

pci_find_root_bus() takes a domain parameter. Currently PCI root buses
with domain other than 0 can't be created, so this is more or less a long
winded way of retrieving the main PCI root bus. Numbered domains don't
actually properly cover the (non x86) possibilities for multiple PCI root...

vmport: Disentangle read handler type from portio

In case the latter may vanish one day, make sure the vmport read handler

pci: Move pci_read_devaddr to pci-hotplug-old.c

pci_read_devaddr() is only used by the legacy functions for the old PCI

Avoid use of static variables: PC systems
