#define	TRACE_MAX_ID   0xffffff
	Maximum ID of a trace entry.
#define	TRACE_LEN(i)   (((i) >> 8) + TRACE_HEADER_LEN)
	Return size (in 16bits words) of the trace entry whose first word is i.
#define	TRACE_LAST_ENTRY   0xffff
	Pattern to mark last trace entry.
#define	TRACE_READY   0x1234
	Pattern to mark than trace buffer is ready.
#define	TRACE_LOCKED   0xdead
