And indeed there is...

long (*__kvm_arch_vm_ioctl)(struct file *filp, unsigned long ioctl, unsigned long arg) = NULL;

Use a different name than __kvm_arch_vm_ioctl and (ideally) make it 
static.

kallsyms_lookup_name("__kvm_arch_vm_ioctl") returns the address of this 
variable from the patch module.
