Move user-visible parts of drivers/s390/crypto/z90crypt.h to include/asm-s390

Also remove Bob Burroughs' email address, since it's no longer valid.

-/**
- * Interface notes:
- *
- * The ioctl()s which are implemented (along with relevant details)
- * are:
- *
- *   ICARSAMODEXPO
- *     Perform an RSA operation using a Modulus-Exponent pair
- *     This takes an ica_rsa_modexpo struct as its arg.
- *
- *     NOTE: please refer to the comments preceding this structure
- *           for the implementation details for the contents of the
- *           block
- *
- *   ICARSACRT
- *     Perform an RSA operation using a Chinese-Remainder Theorem key
- *     This takes an ica_rsa_modexpo_crt struct as its arg.
- *
- *     NOTE: please refer to the comments preceding this structure
- *           for the implementation details for the contents of the
- *           block
- *
- *   Z90STAT_TOTALCOUNT
- *     Return an integer count of all device types together.
- *
- *   Z90STAT_PCICACOUNT
- *     Return an integer count of all PCICAs.
- *
- *   Z90STAT_PCICCCOUNT
- *     Return an integer count of all PCICCs.
- *
- *   Z90STAT_PCIXCCMCL2COUNT
- *     Return an integer count of all MCL2 PCIXCCs.
- *
- *   Z90STAT_PCIXCCMCL3COUNT
- *     Return an integer count of all MCL3 PCIXCCs.
- *
- *   Z90STAT_CEX2CCOUNT
- *     Return an integer count of all CEX2Cs.
- *
- *   Z90STAT_CEX2ACOUNT
- *     Return an integer count of all CEX2As.
- *
- *   Z90STAT_REQUESTQ_COUNT
- *     Return an integer count of the number of entries waiting to be
- *     sent to a device.
- *
- *   Z90STAT_PENDINGQ_COUNT
- *     Return an integer count of the number of entries sent to a
- *     device awaiting the reply.
- *
- *   Z90STAT_TOTALOPEN_COUNT
- *     Return an integer count of the number of open file handles.
- *
- *   Z90STAT_DOMAIN_INDEX
- *     Return the integer value of the Cryptographic Domain.
- *
- *   Z90STAT_STATUS_MASK
- *     Return an 64 element array of unsigned chars for the status of
- *     all devices.
- *       0x01: PCICA
- *       0x02: PCICC
- *       0x03: PCIXCC_MCL2
- *       0x04: PCIXCC_MCL3
- *       0x05: CEX2C
- *       0x06: CEX2A
- *       0x0d: device is disabled via the proc filesystem
- *
- *   Z90STAT_QDEPTH_MASK
- *     Return an 64 element array of unsigned chars for the queue
- *     depth of all devices.
- *
- *   Z90STAT_PERDEV_REQCNT
- *     Return an 64 element array of unsigned integers for the number
- *     of successfully completed requests per device since the device
- *     was detected and made available.
- *
- *   ICAZ90STATUS (deprecated)
- *     Return some device driver status in a ica_z90_status struct
- *     This takes an ica_z90_status struct as its arg.
- *
- *     NOTE: this ioctl() is deprecated, and has been replaced with
- *           single ioctl()s for each type of status being requested
- *
- *   Z90STAT_PCIXCCCOUNT (deprecated)
- *     Return an integer count of all PCIXCCs (MCL2 + MCL3).
- *     This is DEPRECATED now that MCL3 PCIXCCs are treated differently from
- *     MCL2 PCIXCCs.
- *
- *   Z90QUIESCE (not recommended)
- *     Quiesce the driver.  This is intended to stop all new
- *     requests from being processed.  Its use is NOT recommended,
- *     except in circumstances where there is no other way to stop
- *     callers from accessing the driver.  Its original use was to
- *     allow the driver to be "drained" of work in preparation for
- *     a system shutdown.
- *
- *     NOTE: once issued, this ban on new work cannot be undone
- *           except by unloading and reloading the driver.
