[kvm-unit-tests PATCH v4 0/7] s390x: Add base AP support

[Janosch Frank <frankja@linux.ibm.com>]

As KVM supports passing Adjunct Processor (AP) crypto devices to
guests, we should make sure that the interface works as expected.

Three instructions provide the interface to the AP devices:
 - nqap: Enqueues a crypto request
 - dqap: Dequeues a crypto request
 - pqap: Provides information and processes support functions

nqap & dqap work on crypto requests for which we currently don't want
to add tests due to their sheer complexity.

Which leaves us with pqap which is partly emulated for a guest 2 and
hence is a prime target for testing.

v4:
	- Rebase on the cc dirty series
	- Bumped year to 2024
v3:
	- Renamed ap_check() to ap_setup() and added comment
v2:
	- Re-worked the ap_check() function to test for stfle 12 since
          we rely on PQAP QCI in the library functions
	- Re-worked APQN management
	- Fixed faulty loop variable initializers in ap.c
	- Fixed report messages
	- Extended clobber lists
	- Extended length bit checks for nqap
	- Now using ARRAY_SIZE where applicabale
	- NIB is now allocated as IO memory
