Powerpc PCI cleanups (mainly iSeries)

[Stephen Rothwell]

Hi all,

I started out looking for ways to remove our dependencies on pci_dn and
got sidetracked into clening up the iSeries PCI code.  The intention of
the following set of patches is that there be no semantic changes
(mostly).

Overall diffstat looks like this:
 arch/powerpc/kernel/pci-common.c           |   31 +--
 arch/powerpc/kernel/pci_32.c               |    6 +-
 arch/powerpc/kernel/pci_64.c               |   40 +--
 arch/powerpc/kernel/pci_dn.c               |    2 +-
 arch/powerpc/platforms/85xx/mpc85xx_ds.c   |    2 +-
 arch/powerpc/platforms/86xx/mpc86xx_hpcn.c |    2 +-
 arch/powerpc/platforms/iseries/pci.c       |  426 +++++++++++-----------------
 arch/powerpc/platforms/iseries/pci.h       |   20 +-
 arch/powerpc/platforms/iseries/setup.c     |    2 +
 arch/powerpc/platforms/iseries/vpdinfo.c   |   17 +-
 arch/powerpc/platforms/powermac/pci.c      |    2 +-
 arch/powerpc/platforms/pseries/iommu.c     |    2 +-
 include/asm-powerpc/pci-bridge.h           |  156 ++++------
 include/asm-powerpc/ppc-pci.h              |    3 -
 14 files changed, 266 insertions(+), 445 deletions(-)

This entire set sits on top of benh's "Make isa_mem_base common to 32 and
64 bits" and "Merge pci_process_bridge_OF_ranges" patches and my
"iommu_free_table doesn't need the device_node" and "pSeries: remove
dependency on pci_dn bussubno" patches posted earlier.
