Subject: kvm: no hardware support

I enable vmx and svm option for KVM in .config

on amd SVM enable system

vmx get tried at first

and get
kvm: no hardware support

Calling initcall 0xffffffff80c2d465: vmx_init+0x0/0x119()
kvm: no hardware support
initcall 0xffffffff80c2d465: vmx_init+0x0/0x119() returned -95.
initcall 0xffffffff80c2d465 ran for 2 msecs: vmx_init+0x0/0x119()
initcall at 0xffffffff80c2d465: vmx_init+0x0/0x119(): returned with
error code -95

Calling initcall 0xffffffff80c2d57e: svm_init+0x0/0x13()
initcall 0xffffffff80c2d57e: svm_init+0x0/0x13() returned 0.
initcall 0xffffffff80c2d57e ran for 0 msecs: svm_init+0x0/0x13()

suggest you add .name in ops like "vmx" or "svm"

and that message can become
kvm: no hardware support for vmx
or
kvm: no hardware support for svm

or just remove that line.
        }

        if (!ops->cpu_has_kvm_support()) {
-                printk(KERN_ERR "kvm: no hardware support\n");
                r = -EOPNOTSUPP;
                goto out;
        }
