Machine vector selection has always been a bit of a hack given how
early in system boot it needs to be done. Services like ACPI namespace
are not available and there are non-trivial problems to moving them to
early boot. However, there's no reason we can't change to a different
machvec later in boot when the services we need are available. By
adding a entry point for later initialization of the swiotlb, we can add
an error path for the hpzx1 machevec initialization and fall back to the
DIG machine vector if IOMMU hardware isn't found in the system. Since
ia64 uses 4GB for zone DMA (no ISA support), it's trivial to allocate a
contiguous range from the slab for bounce buffer usage.Signed-off-by: Alex Williamson

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!
