Abstract

This article describes a special control for the execution of the instructions INSERT STORAGE KEY (ISK), RESET REFERENCE BIT (RRB), and SET STORAGE KEY (SSK) to prevent an operating system designated and implemented for 2KB storage-key-block size from executing incorrectly on a CPU which is implemented for a 4KB storage-key-block size.
