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!

+/* Board configuration array.
+ * This array defines the hardware irq and address for up to IP2_MAX_BOARDS
+ * (4 supported per ip2_types.h) ISA board addresses and irqs MUST be specified,
+ * PCI and EISA boards are probed for and automagicly configed
+ * iff the addresses are set to 1 and 2 respectivily.
+ *    0x0100 - 0x03f0 == ISA
+ *               1        == PCI
+ *               2        == EISA
+ *               0        == (skip this board)
+ * This array defines the hardware addresses for them. Special 
+ * addresses are EISA and PCI which go sniffing for boards. 
+
+ * In a multiboard system the position in the array determines which port
+ * devices are assigned to each board: 
+ *              board 0 is assigned ttyF0.. to ttyF63, 
+ *              board 1 is assigned ttyF64  to ttyF127,
+ *              board 2 is assigned ttyF128 to ttyF191,
+ *              board 3 is assigned ttyF192 to ttyF255. 
+ *
+ * In PCI and EISA bus systems each range is mapped to card in 
+ * monotonically increasing slot number order, ISA position is as specified
+ * here.
+
+ * If the irqs are ALL set to 0,0,0,0 all boards operate in 
+ * polled mode. For interrupt operation ISA boards require that the IRQ be 
+ * specified, while PCI and EISA boards any nonzero entry 
+ * will enable interrupts using the BIOS configured irq for the board. 
+ * An invalid irq entry will default to polled mode for that card and print
+ * console warning.
+ 
+ * When the driver is loaded as a module these setting can be overridden on the 
+ * modprobe command line or on an option line in /etc/modprobe.conf.
+ * If the driver is built-in the configuration must be 
+ * set here for ISA cards and address set to 1 and 2 for PCI and EISA.
+ *
+ * Here is an example that shows most if not all possibe combinations:
+
+ *static ip2config_t ip2config =
+ *{
+ *      {11,1,0,0},             // irqs
+ *      {                               // Addresses
+ *              0x0308,         // Board 0, ttyF0   - ttyF63// ISA card at io=0x308, irq=11
+ *              0x0001,         // Board 1, ttyF64  - ttyF127//PCI card configured by BIOS
+ *              0x0000,         // Board 2, ttyF128 - ttyF191// Slot skipped
+ *              0x0002          // Board 3, ttyF192 - ttyF255//EISA card configured by BIOS
+ *                                                                                               // but polled not irq driven
+ *      }
+ *};

+ /* this structure is zeroed out because the suggested method is to configure
+  * the driver as a module, set up the parameters with an options line in
+  * /etc/modprobe.conf and load with modprobe or kmod, the kernel
+  * module loader
+  */
+
+ /* This structure is NOW always initialized when the driver is initialized.
