Subject: Linux-2.6.12-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!

+ *      sercons.c is designed to allow the three different kinds 
+ *      of serial devices under the decstation world to co-exist
+ *      in the same kernel.  The idea here is to abstract 
+ *      the pieces of the drivers that are common to this file
+ *      so that they do not clash at compile time and runtime.
+ *
+ * HK 16-SEP-1998 v0.002
+ *      removed the PROM console as this is not a real serial
+ *      device. Added support for PROM console in drivers/char/tty_io.c
+ *      instead. Although it may work to enable more than one 
+ *      console device I strongly recommend to use only one.
