 We already have it in our data. I took a quick look at that, but kernel needs 
patching. IIRC reset
for secondary vCPUs happens inside kernel's PSCI code, before primary tells it 
to start up. You
cannot separate these two events.
 In a short: you can use KVM_SET_ONE_REG for the MPIDR, and the value will go 
into kernel, but as
soon as you call KVM_VCPU_RUN for the secondary, it gets reset.

 And my emails do not go to the list indeed... Don't understand why.
