I think it comes from

static void add_atomic_switch_msr_special(struct vcpu_vmx *vmx,
                unsigned long entry, unsigned long exit,
                unsigned long guest_val_vmcs, unsigned long host_val_vmcs,
                u64 guest_val, u64 host_val)
{
        vmcs_write64(guest_val_vmcs, guest_val);
        if (host_val_vmcs != HOST_IA32_EFER)
                vmcs_write64(host_val_vmcs, host_val);
        vm_entry_controls_setbit(vmx, entry);
        vm_exit_controls_setbit(vmx, exit);
}


and it can be fixed just with __always_inline.
