dynamic changes for HW Crypto definitions in z/VM w/o IPL of z/VM

Allow dynamic changes of HW crypto support definitions in z/VM without the need of performing an IPL of z/VM
In an existing z/VM environment we had assigned a HW-Crypto queue to a z/VM LPAR (processor 1 Domain 4). When adding a CRYPTO statement to a Linux guest (CRYPTO DOMAIN 4 APDED 1) we could not used this crypto queue wit hthe Linux guest. We know the limitation, that an IPL of the Linux guest is necessary to use the new definitions in the directory. But the IPL of the Linux guest did not help. After discussion with Brian Hugenbruch (Endicott) it turned out that we need an IPL of the complete z/VM system (with a lot of Linux guests!!!!), as the crypto queue of proc 1 domain 4 had been used in the past for another Linux guest as shared queue (APVIRT). Even the other guest is no more existing, the system still keeps the queue and does not "free" it or gives it back to be used as APDED. To free it and to use it, an IPL of the complete z/VM system is necessary. This behaviour is in general very anoying as it will lead to a complete disruption of many Linux systems, which might be used for production!
Therefore 1st priority: remove all restrictions, which require a IPL of z/VM in the area of HW crypto support.
2nd priority: Changes in directory with CRYPTO statement should not require a IPL of this guest.

Add. question: how can I make this requirement public? (as soon as I specified "z/VM" as product the visibility changed from "public" to "private").
