No functional change, just identify the device nicely:
-IOC: Unknown (103c:12ec) 0.1 HPA 0xf8020002000 IOVA space 1024Mb at 0x40000000
+IOC: sx2000 0.1 HPA 0xf8020002000 IOVA space 1024Mb at 0x40000000
We used to create fake PCI devices for these chips, but we no longer do that.
So I don't think there's any reason to touch pci_ids.h now.

This fixes a couple of bugs in the zx1/sx1000 sba_iommu. These are
all pretty low likelihood of hitting. The first problem is a simple off
by one, deep in the sba_alloc_range() error path. Surrounding that was
a lock ordering problem that could have potentially deadlocked with the
order the locks are grabbed in sba_unmap_single(). I moved the resource
locking into sba_search_bitmap() to prevent this. Finally, there's a
potential race between unmapping pdir entries and marking incoming DMA
pages clean. If you see any oddities, please let me know, but I've
tested it pretty thoroughly here. Tony, please apply. Thanks,
BTW, many of the options in this driver not on by default are becoming
more and more broken. I'll be working on some patches to clean them
out, but I wanted to get this bug fix out first.

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!
