s390/zcrypt: Show load of cards and queues in sysfs Show the current load value of cards and queues in sysfs. The load value for each card and queue is maintained by the zcrypt device driver for dispatching and load balancing requests over the available devices. This patch provides the load value to userspace via a new read only sysfs attribute 'load' per card and queue.

s390: crypto: Remove redundant license text Now that the SPDX tag is in all drivers/s390/crypto/ files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

s390: crypto: add SPDX identifiers to the remaining files It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/s390/crypto/ files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

s390/zcrypt: Rework debug feature invocations. Rework the debug feature calls and initialization. There are now two debug feature entries used by the zcrypt code. The first is 'ap' with all the AP bus related stuff and the second is 'zcrypt' with all the zcrypt and devices and driver related entries. However, there isn't much traffic on both debug features. The ap bus code emits only some debug info and for zcrypt devices on appearance and disappearance there is an entry written. The new dbf invocations use the sprintf buffer layout, whereas the old implementation used the ascii dbf buffer. There are now 5*8=40 bytes used for each entry, resulting in 5 parameters per call. As the sprintf buffer needs a format string the first parameter provides this and so up to 4 more parameters can be used. Alltogehter the new layout should be much more human readable for customers and test.

s390/zcrypt: add multi domain support Currently the ap infrastructure only supports one domain at a time. This feature extends the generic cryptographic device driver to support multiple cryptographic domains simultaneously. There are now card and queue devices on the AP bus with independent card and queue drivers. The new /sys layout is as follows: /sys/bus/ap devices <xx>.<yyyy> -> ../../../devices/ap/card<xx>/<xx>.<yyyy> ... card<xx> -> ../../../devices/ap/card<xx> ... drivers <drv>card card<xx> -> ../../../../devices/ap/card<xx> <drv>queue <xx>.<yyyy> -> ../../../../devices/ap/card<xx>/<xx>.<yyyy> ... /sys/devices/ap card<xx> <xx>.<yyyy> driver -> ../../../../bus/ap/drivers/<zzz>queue ... driver -> ../../../bus/ap/drivers/<drv>card ... The two digit <xx> field is the card number, the four digit <yyyy> field is the queue number and <drv> is the name of the device driver, e.g. "cex4". For compatability /sys/bus/ap/card<xx> for the old layout has to exist, including the attributes that used to reside there. With additional contributions from Harald Freudenberger and Martin Schwidefsky.
