Hi Peter,
After discussing with Kirill, I changed the way of how to handle the per-cpu
initialization, and in the new version (v10, just sent) I don't need the
schedule_on_each_cpu_cond_locked() anymore, because I essentially moved such
handling out of TDX host series to KVM. I'll use your patch if the review found
we still need to handle it. Thanks!
