In addition to that some prereqs for the ap/crypto driver are necessary

ea3c4185efb3 s390/zcrypt: Add ZAPQ inline function.
df80c0383133 s390/zcrypt: Review inline assembler constraints.
f1b0a4343c41 s390/zcrypt: Integrate ap_asm.h into include/asm/ap.h.
2395103b3fbf s390/zcrypt: fix ap_instructions_available() returncodes
7e0bdbe5c21c s390/zcrypt: AP bus support for alternate driver(s)
3d8f60d38e24 s390/zcrypt: hex string mask improvements for apmask and aqmask.
fa108f95c676 (tag: s390-4.19-3) s390/zcrypt: remove VLA usage from the AP bus

So the git commands for 4.18 would be:

$ git cherry-pick 9ea597286570 3194cdb71190 e585b24aeb44 1fde573413b5 \
65f06713d3fa 96d152bdc987 3211da0c0b54 3b1eab7fb9da 81b2b4b76a73 42104598ef2e \

9ee71f20cb8d 37940fb0b6a2 112c24d4dc48 492a6be197c0 # kvm/next

(112c24d... KVM: s390: CPU model support for AP virtualization has a trivial merge conflict with the etoken patch)
