pci: allow 0 address for PCI IO/MEM regions
Some kernels program a 0 address for io regions. PCI 3.0 spec section 6.2.5.1 doesn't seem to disallow this. based on patch by Michael Roth <mdroth@linux.vnet.ibm.com> Add pci_allow_0_addr in MachineClass to conditionally allow addr 0 for pseries, as this can break other architectures. This patch allows to hotplug PCI card in pseries machine, as the first added card BAR0 is always set to 0 address. This as a temporary hack, waiting to fix PCI memory priorities for more machine types... Signed-off-by: Laurent Vivier <lvivier@redhat.com> Reviewed-by: Michael S.
