Comments

• This enhancement makes z/VM's APVIRT crypto message
  processing more event-driven by using crypto-related
  interruptions to drive crypto work.
  
  The following externals have been added for this support:
  1. The CRYPTO APVIRTUAL system configuration statement is
     updated to allow a new POLLING option.  This option
     can be used to specify whether CP uses polling or
     interruptions to drive the processing of crypto work
     that is assigned to the shared pool.  This statement
     is documented in chapter 6 of CP Planning and
     Administration (SC24-6271-10).
  2. A new SET CRYPTO command is introduced and can be used
     to specify whether CP uses polling or interruptions
     to drive the processing of crypto work that is
     assigned to the shared pool.  This command is
     documented in chapter 2 of the CP Commands and
     Utilities Reference (SC24-6268-11).
  3. The QUERY CRYPTO command is enhanced to accept
     APVIRTUAL POLLING as operands.
     QUERY CRYPTO APVIRTUAL POLLING can be used to request
     a display of the polling setting for the shared pool.
     This command is documented in chapter 2 of the
     CP Commands and Utilities Reference (SC24-6268-11).
  4. One new message is added.  This message is documented
     in chapter 3 of CP Messages and Codes (GC24-6270-10).
     171301  E A required facility is not available to
               allow Crypto to operate with polling off.
               Polling remains on.
