155: * XPR(XPR_SYSCALLS, "syscall: %d, 0x%x\n", syscallno, arg1, 0,0,0);

161: * a circular buffer. The actual printf processing is delayed until after
162: * the buffer has been collected. It is assumed that the text/data segments
163: * of the kernel can easily be reconstructed in a post-processor which
164: * performs the printf processing.
