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 bios low-memory structure
+ *
+ * Some of the variables in here can be used to set parameters that
+ * are stored in NVRAM and will retain their old values the next time
+ * the card is brought up.  To use the values stored in NVRAM, the
+ * parameter should be set to "all ones".  This tells the firmware to
+ * use the NVRAM value or a suitable default.  The value that is used
+ * will be stored back into this structure by the firmware.  If the
+ * value of the variable is not "all ones", then that value will be
+ * used and will be stored into NVRAM if it isn't already there.
+ * The variables this applies to are the following:
+ *	Variable	Set to:		Gets default of:
+ *	bc_hashexpire	-1		300	(5 minutes)
+ *	bc_spantree	-1		1	(spanning tree on)
+ *	bc_ipaddr	FF:FF:FF:FF	0	(no SNMP IP address)
+ *	bc_ipxnet	FF:FF:FF:FF	0	(no SNMP IPX net)
+ *	bc_iptrap	FF:FF:FF:FF	0	(no SNMP IP trap address)
+ *
+ * Some variables MUST have their value set after the firmware
+ * is loaded onto the board, but before the processor is released.
+ * These are:
+ *	bc_host		0 means no host "port", run as standalone switch.
+ *			1 means run as a switch, with a host port. (normal)
+ *			2 means run as multiple NICs, not as a switch.
+ *			-1 means run in diagnostics mode.
+ *	bc_nowait
+ *	bc_hostarea_len
+ *	bc_filter_len
