 *  FACILITY:
 *
 *      VMS Executive (SYS)
 *
 *  ABSTRACT:
 *
 *      This module contains definitions for the IPF compatibility 
 *      routines for the Alpha unprivileged queue PALcode instructions.
 *
 *  AUTHOR:
 *
 *      Dennis Mattoon
 *
 *  CREATION DATE:
 *
 *      06-JUN-2002
 *
 *  MODIFICATION HISTORY:
 *
 *	X-5	DJM		Dennis Mattoon		20-NOV-2002
 *		Moved more symbol definitions and typedefs over to
 *		sys_pal_qinst.c.  The symbols and struct defs do not
 *		need to be availble globaly.  They are only used by
 *		the queue instruction system service routines.
 *
 *	X-4	DJM		Dennis Mattoon		15-NOV-2002
 *		Moved QINST$L_GLOBAL and QINST$Q_GLOBAL declarations
 *		out of this module and into SYS_PAL_QINST.C to avoid
 *		"multiply defined" linker warnings...
 *
 *
 *	X-3	DJM		Dennis Mattoon		12-NOV-2002
 *		Redefined memory-resident self-relative queue
 *		instruction builtins to point at corresponding
 *		non-resident versions.  See comment below for
 *		more details.
 *
 *      X-2     DJM             Dennis Mattoon          05-NOV-2002
 *		Removed Alpha specific code (queue system services
 *		are now IA64 only) and fixed some status values
 *		that did not match the original PALcode definition.
 *
 *      X-1     DJM             Dennis Mattoon          06-JUN-2002
 *              Original version.

/* They get redefined because we are unable to safely implement     */
/* system service routines that emulate their behaviour exactly.    */
/* This is because we have to make sure that isertions and removals */
/* to and from queues are non-interruptable. To ensure this we have */
/* to execute in kernel mode at elevated IPL. If we're callable     */
/* from user mode and executing at high ipl we MUST make sure that  */
/* we do not incur any memory management exceptons.  In order to    */
/* do this we have to make certain alignment and memory management  */
/* checks, thus negating the whole purpose of executing the memory  */
/* resident version of any queue instruction in the first place.    */
