/*
 * If you change this, be sure to make appropriate corresponding changes
 * to kern/errmsg.h as well. You might also want to change the man page
 * for errno to document the new error.
 *
 * This has been changed relative to OS/161 1.x to make the grouping
 * more logical.
 *
 * Also note that this file has to work from assembler, so it should
 * contain only symbolic constants.
