charset="utf-8" Drop the manual initialization of maxphyaddr and reserved_gpa_bits during vCPU creation now that kvm_arch_vcpu_create() unconditionally invokes kvm_vcpu_after_set_cpuid(), which handles all such CPUID caching. None of the helpers between the existing code in kvm_arch_vcpu_create() and the call to kvm_vcpu_after_set_cpuid() consume maxphyaddr or reserved_gpa_bits (though auditing vmx_vcpu_create() and svm_vcpu_create() isn't exactly easy).
