Linux-2.6.12-rc2v2.6.12-rc2

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!

+ * IXP4xx provides two methods of accessing PCI memory space:

+ *    To access PCI via this space, we simply ioremap() the BAR
+ *    into the kernel and we can use the standard read[bwl]/write[bwl]
+ *    macros. This is the preffered method due to speed but it
+ *    limits the system to just 64MB of PCI memory. This can be 
+ *    problamatic if using video cards and other memory-heavy
+ *    targets.
+ *
+ * 2) If > 64MB of memory space is required, the IXP4xx can be configured
+ *    to use indirect registers to access PCI (as we do below for I/O
+ *    transactions). This allows for up to 128MB (0x48000000 to 0x4fffffff)
+ *    of memory on the bus. The disadvantadge of this is that every 
+ *    PCI access requires three local register accesses plus a spinlock,
+ *    but in some cases the performance hit is acceptable. In addition,
+ *    you cannot mmap() PCI devices in this case.
