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!

+IP dynamic address hack-port v0.03
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+This stuff allows diald ONESHOT connections to get established by
+dynamically changing packet source address (and socket's if local procs).
+It is implemented for TCP diald-box connections(1) and IP_MASQuerading(2).
+
+If enabled[*] and forwarding interface has changed:
+  1)  Socket (and packet) source address is rewritten ON RETRANSMISSIONS
+      while in SYN_SENT state (diald-box processes).
+  2)  Out-bounded MASQueraded source address changes ON OUTPUT (when
+      internal host does retransmission) until a packet from outside is
+      received by the tunnel.
+
+This is specially helpful for auto dialup links (diald), where the
+``actual'' outgoing address is unknown at the moment the link is
+going up. So, the *same* (local AND masqueraded) connections requests that
+bring the link up will be able to get established.
+
+[*] At boot, by default no address rewriting is attempted. 
+  To enable:
+     # echo 1 > /proc/sys/net/ipv4/ip_dynaddr
+  To enable verbose mode:
+     # echo 2 > /proc/sys/net/ipv4/ip_dynaddr
+  To disable (default)
+     # echo 0 > /proc/sys/net/ipv4/ip_dynaddr
+
+Enjoy!
