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.
It wasn't tagged for the stable kernels, so we didn't pick it up :(
Have now done so, thanks.
