2025-01-07	s390/crypto/cpacf: Constify 'struct bin_attribute'	Thomas Weißschuh
	The sysfs core now allows instances of 'struct bin_attribute' to be moved into read-only memory. Make use of that to protect them against accidental or malicious modifications.

2024-09-12	s390/crypto: Display Query and Query Authentication Information in sysfs	Finn Callies
	Displays the query (fc=0) and query authentication information (fc=127) as binary in sysfs per CPACF instruction. Files are located in /sys/devices/system/cpu/cpacf/. These information can be fetched via asm already except for PCKMO because this instruction is privileged. To offer a unified interface all CPACF instructions will have this information displayed in sysfs in files <instruction>_query_raw and <instruction>_query_auth_info_raw. A new tool introduced into s390-tools called cpacfinfo will use this information to convert and display in human readable form.
