 * Each board needs to define the following functions:
 *
 * int	_splraise(int);
 * int	_spllower(int);
 * void	splx(int);
 * void	_setsoftintr(int);
 *
 * These may be defined as functions, static __inline functions, or macros,
 * but there must be a _spllower() and splx() defined as functions callable
 * from assembly language (for cpu_switch()).  However, since it's quite
 * useful to be able to inline splx(), you could do something like the
 * following:
 *
 * in <boardtype>_intr.h:
 * 	static __inline int
 *	boardtype_splx(int spl)
 *	{...}
 *
 *	#define splx(nspl)	boardtype_splx(nspl)
 *	...
 * and in boardtype's machdep code:
 *
 *	...
 *	#undef splx
 *	int
 *	splx(int spl)
 *	{
 *		return boardtype_splx(spl);
 *	}
