/**
 *  This file handles all the PSP-specific kernel setup and exit stuff.
 *
 *  Is there some general interest for this file, so that we can place it
 *  somewhere in the compiler toolchain include path? 
 *
 *  Usage: Simply add 
 *            -DMODULE_NAME="your-module-name" psp-setup.c
 *         to the LFLAGS or LDFLAGS of your project, so that this file is
 *         compiled in when gcc collects and links the final ELF binary.
 *
 *  Options:
 *         -DMODULE_NAME="name" -- set the name (default NONAME)
 *         -DMODULE_ATTR=0      -- module attributes (default 0)
 *         -DVERSION_MAJOR=1    -- version 1.x (default 1)
 *         -DVERSION_MINOR=0    -- version x.0 (default 0)
 *
 *  Note:  The linker flags and library lists need to be placed after this
 *         entry on the LFLAG or LDFLAGS command line, otherwise gcc won't
 *         be able to to resolve all symbols.
