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!

+ * include/linux/vt_buffer.h -- Access to VT screen buffer
+ *
+ * (c) 1998 Martin Mares <mj@ucw.cz>
+ *
+ * This is a set of macros and functions which are used in the
+ * console driver and related code to access the screen buffer.
+ * In most cases the console works with simple in-memory buffer,
+ * but when handling hardware text mode consoles, we store
+ * the foreground console directly in video memory.
