 Hi!

> Well KVM side should be fixed instead of driving us along wrong route.

 I have studied the question a bit more, and i discovered that MPIDR access on ARM is not
trapped by KVM. And guest would always get the same value as host would. Theoretically you
could modify the kernel so that PSCI accepts IDs set by qemu, but in this case we would
have inconsistency between device tree and real IDs. And there seems to be no way round.

Kind regards,
