Subject: [PATCH v1 0/5] KVM: s390: selftests: Add regression tests for CPU subfunctions

This patch series introduces a set of regression tests for various s390x 
CPU subfunctions in KVM. The tests ensure that the KVM implementation accurately
reflects the behavior of actual CPU instructions for these subfunctions.

The series adds tests for a total of 15 instructions across five patches,
covering a range of operations including sorting, compression, and various
cryptographic functions. Each patch follows a consistent testing pattern:

1. Obtain the KVM_S390_VM_CPU_MACHINE_SUBFUNC attribute for the VM.
2. Execute the relevant asm instructions. 
3. Compare KVM-reported results with direct instruction execution results.

Testing has been performed on s390x hardware with KVM support. All tests
pass successfully, verifying the correct implementation of these
subfunctions in KVM.
