[PATCH] Altix system controller communication driver

[PATCH] Altix system controller communication driver

drivers/char/Kconfig
    Make a config option for the SGI Altix system controller
    communication driver.

drivers/char/Makefile
    Add an object file target for the SGI Altix system controller
    communication driver.

drivers/char/snsc.c
    This file implements a driver that allows an application to
    communicate with the SGI Altix system controller network. Most of
    the heavy lifting is done in SAL in order to allow Linux run-time
    applications to share the system controller link(s) with SAL
    run-time services.

drivers/char/snsc.h
    Macros and data types for the Altix system controller driver
    (drivers/char/snsc.c).

drivers/serial/sn_console.c
    Modify the SGI Altix console driver to share an interupt with the
    system controller communication driver.

include/asm-ia64/sn/sn_sal.h
    Provide an interface to the SAL runtime services that allow the
    kernel or user applications to send/receive arbitary system
    controller data.
