		* 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

		*
		* ICARSACRT
		* Perform an RSA operation using a Chinese-Remainder Theorem key

		*
		* 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

		* 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.
