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!

9 | * the pieces of the drivers that are common to this file | ||

13 | * removed the PROM console as this is not a real serial | ||
14 | * device. Added support for PROM console in drivers/char/tty_io.c | ||
15 | * instead. Although it may work to enable more than one | ||
16 | * console device I strongly recommend to use only one. | ||
