I actually ended-up implementing a similar patch as part of my 'first run' series[1], though I moved the mapping to the point where we finalise the vcpu as that's where the allocation takes place. Do you see any potential issue with that approach?
Nope, and in fact I think your patch should allow to simplify a bit kvm_arm_vcpu_destroy() for me, as checking arch.sve_state != NULL would now be sufficient to know if the sve state has been shared -- checking arch.has_run_once is no longer needed. I'll base v2 on this. Thanks!
