KVM: s390: Manually invoke vcpu setup during kvm_arch_vcpu_create()
Rename kvm_arch_vcpu_setup() to kvm_s390_vcpu_setup() and manually call the new function during kvm_arch_vcpu_create(). Define an empty kvm_arch_vcpu_setup() as it's still required for compilation. This is effectively a nop as kvm_arch_vcpu_create() and kvm_arch_vcpu_setup() are called back-to-back by common KVM code. Obsoleting kvm_arch_vcpu_setup() paves the way for its removal. Note, gmap_remove() is now called if setup fails, as s390 was previously freeing it via kvm_arch_vcpu_destroy(), which is called by common KVM code if kvm_arch_vcpu_setup() fails. No functional change intended. Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com> Reviewed-by: Cornelia Huck <cohuck@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
