Brown paper bag day, previous commit wouldn't work very well with modules
enabled. Move the exports into the ifdef.

"iomap: make IOPORT/PCI mapping functions conditional"

Broke powerpc build without CONFIG_PCI as we would still define
pci_iomap(), which overlaps with the new empty inline in the headers.

Make our implementation conditional on CONFIG_PCI

The patch adds support for the 64-bit resources to the PCI
iomap code.

This patch uses the newly added functions for testing if an address is
an ISA or PCI IO port to properly unmap things in pci_iounmap that
aren't such ports.  Without that, drivers using the iomap API will never
actually unmap resources, which on IBM server machines will prevent
hot-unplug of the corresponding HW adapters.

powerpc: Merge 32 and 64 bits asm-powerpc/io.h

The rework on io.h done for the new hookable accessors made it easier,
so I just finished the work and merged 32 and 64 bits io.h for arch/powerpc.

arch/ppc still uses the old version in asm-ppc, there is just too much gunk
in there that I really can't be bothered trying to cleanup.

Cleanup patch which removes the io_page_mask.  It fixes the reset on
some e1000 devices which is needed for clean kexec reboots.  The legacy
devices which broke with this patch (parallel port and PC speaker) have
now been fixed in Linus' tree.

This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

Also deletes files in arch/ppc64 that are no longer used now that
we don't compile with ARCH=ppc64 any more.

that do export big-endian I/O memory.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
