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!

+	  The Common Flash Interface specification was developed by Intel,
+	  AMD and other flash manufactures that provides a universal method
+	  for probing the capabilities of flash devices. If you wish to
+	  support any device that is CFI-compliant, you need to enable this
+	  option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>

+	  This option enables JEDEC-style probing of flash chips which are not
+	  compatible with the Common Flash Interface, but will use the common
+	  CFI-targetted flash drivers for any chips which are identified which
+	  are in fact compatible in all but the probe method. This actually
+	  covers most AMD/Fujitsu-compatible chips, and will shortly cover also
+	  non-CFI Intel chips (that code is in MTD CVS and should shortly be sent

+	  are expected to be wired to the CPU in 'host-endian' form. 
+	  Specific arrangements are possible with the BIG_ENDIAN_BYTE and
+	  LITTLE_ENDIAN_BYTE, if the bytes are reversed.
+
+	  If you have a LART, on which the data (and address) lines were
+	  connected in a fashion which ensured that the nets were as short

+	  This option does not enable any code directly, but will allow you to
+	  select some other chip drivers which are now considered obsolete,
