minimal alignment of p2p bars according to the argument.

On some powerpc platforms, device BARs need to be assigned to separate
"segments" of the address space in order for the error isolation and HW
virtualization mechanisms (EEH) to work properly. Those "segments" have
a minimum size that can be fairly large (16M). In order to be able to
use the generi
The patch changes the variable name for function find_pci_host_bridge()
so that it looks more meaningful. More specificly, the "bus" has been
replaced with "root_bus".

The patch changes function pbus_size_io() and pbus_size_mem() to
do resource (I/O, memory and prefetchable memory) reassignment
based on the minimal alignments from the p2p bridge.

The patch fiddles with the those functions used to do conversion
between PCI and CPU address. More specificly, 2 functions are
involved: pcibios_bus_to_resource() and pcibios_resource_to_bus()

The patch makes function find_pci_host_bridge() global so that the
platforms (e.g. PPC) can access pci_host_bridge.

sysfs files are created. But there is no code to remove these files. The patch
