s390/zcrypt: remove CEX2 and CEX3 device drivers Remove the legacy device driver code for CEX2 and CEX3 cards. The last machines which are able to handle CEX2 crypto cards are z10 EC first available 2008 and z10 BC first available 2009. The last machines able to handle a CEX3 crypto card are z196 first available 2010 and z114 first available 2011. Please note that this does not imply to drop CEX2 and CEX3 support in general. With older kernels on hardware up to the aforementioned machine models these crypto cards will get support by IBM. The removal of the CEX2 and CEX3 device drivers code opens up some simplifications, for example support for crypto cards without rng support can be removed also.

s390/zcrypt: zcrypt device driver cleanup Some cleanup in the s390 zcrypt device driver: - Removed fragments of pcixx crypto card code. This code can't be reached anymore because the hardware detection function does not recognize crypto cards < CEX2 since commit f56545430736 ("s390/zcrypt: Introduce QACT support for AP bus devices.") - Rename of some files and driver names which where still reflecting pcixx support to cex2a/cex2c. - Removed all the zcrypt version strings in the file headers. There is only one place left - the zcrypt.h header file is now the only place for zcrypt device driver version info. - Zcrypt version pump up from 2.2.0 to 2.2.1.

s390/zcrypt: code beautify Code beautify by following most of the checkpatch suggestions: - SPDX license identifier line complains by checkpatch - missing space or newline complains by checkpatch - octal numbers for permssions complains by checkpatch - renaming of static sysfs functions complains by checkpatch - fix of block comment complains by checkpatch - fix printf like calls where function name instead of %s __func__ was used - __packed instead of __attribute__((packed)) - init to zero for static variables removed - use of DEVICE_ATTR_RO and DEVICE_ATTR_RW macros No functional code changes or API changes!

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/comments: unify copyright messages and remove file names Remove the file name from the comment at top of many files. In most cases the file name was wrong anyway, so it's rather pointless. Also unify the IBM copyright statement. We did have a lot of sightly different statements and wanted to change them one after another whenever a file gets touched. However that never happened. Instead people start to take the old/"wrong" statements to use as a template for new files. So unify all of them in one go. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

[S390] zcrypt: support for 4096 bit keys for cex3a Definitions for CEX3 card types are changed to support 4096 bit RSA keys. Also new structs for the accelerator mode are needed. Additionaly when checking the length of key parts, the case for bigger (4096 bit) keys is needed.

[S390] zcrypt secure key cryptography extension. Allow the user space to send extended cprb messages directly to the PCIXCC / CEX2C cards. This allows the CCA library to construct special crypto requests that use "secure" keys that are stored on the card.
