That list is missing commit 6470accc7ba9 ("KVM: x86: hyper-v: Avoid calling kvm_make_vcpus_request_mask() with vcpu_mask==NULL") to fulfill the prerequisite of "KVM: Optimize kvm_make_vcpus_request_mask() a bit".
Right now the kvm selftests trigger a kernel NULL deref for the hyperv test, making the system hang.
Please consider applying commit 6470accc7ba9 for the next v5.15.x release.
Thanks, Mathias
