I have addressed your comment about kvm_arch_init_vcpu() function
([RFC PATCH V2 4/6] target-arm: Implement kvm_arch_reset_vcpu() for KVM ARM64)
in -
[RFC PATCH V3 6/7] target-arm: Common kvm_arm_vcpu_init() for KVM ARM
and KVM ARM64
[RFC PATCH V3 7/7] target-arm: Implement kvm_arch_reset_vcpu() for KVM ARM64

Regarding comment about migration incompatibility:
([RFC PATCH V2 3/6] target-arm: Enable KVM_ARM_VCPU_PSCI_0_2 feature
when possible)

During v1 patchset of Christoffer mentioned that he will address it
during migration of armv8.
But till that time can we go ahead with current approach, I can put a
comment about this in code ?
