This patch adds workaround for PPC 440GX erratum 440_43. According to
this erratum spurious MachineChecks (caused by L1 cache parity) can
happen during DataTLB miss processing. We disable L1 cache parity
checking for 440GX rev.C and rev.F

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.

Fix 44x early serial debugging for big RAM configurations (more than 512M).
We cannot use default OpenBIOS virtual mapping, because it interferes with
pinned TLB entry.
While we are at it, move early UART mapping to TLB slot 0, so it can
survive longer during boot process (slot 1 is used by the first ioremap
call, effectively killing UART mapping if it occupies this slot). Also,
change UART TLB entry size to 4K (256M is too much for a bunch of registers
:). Squash some warnings on the way.
Tested on Ebony and Ocotea with 1G of RAM.
Thanks to Scott Coulter <scott.coulter@cyclone.com> for diagnosing this
problem.

* ->io_base_virt in struct pci_controller is iomem pointer. Marked as such.
Most of the places that used it are already annotated to expect iomem.
* places that did gratitious (and wrong) casts a-la
isa_io_base = (unsigned long)ioremap(...);
hose->io_base_virt = (void *)isa_io_base;
turned into
hose->io_base_virt = ioremap(...);
isa_io_base = (unsigned long)hose->io_base_virt;
* pci_bus_io_base() annotated as returning iomem pointer.

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!
