 * Include file for xpr circular buffer silent tracing.  
 *
 */
/*
 * If the kernel flag XPRDEBUG is set, the XPR macro is enabled.  The 
 * macro should be invoked something like the following:
 *	XPR(XPR_SYSCALLS, "syscall: %d, 0x%x\n", syscallno, arg1, 0,0,0);
 * which will expand into the following code:
 *	if (xprflags & XPR_SYSCALLS)
 *		xpr("syscall: %d, 0x%x\n", syscallno, arg1, 0,0,0);
 * Xpr will log the pointer to the printf string and up to 5 arguements,
 * along with a timestamp and cpuinfo (for multi-processor systems), into
 * a circular buffer.  The actual printf processing is delayed until after
 * the buffer has been collected.  It is assumed that the text/data segments
 * of the kernel can easily be reconstructed in a post-processor which
 * performs the printf processing.
 *
 * If the XPRDEBUG compilation switch is not set, the XPR macro expands 
 * to nothing.
