Export access_remote_vm as GPL symbol to allow debuggers (eudebug) to access and modify memory in target VMs by tracking VM_BIND operations. While access_process_vm() is already exported, it would require maintaining task references in the debugger. Since the mm reference is already present in the userptr's mm notifier implementation, exporting access_remote_vm allows that existing reference to be used directly without needing to obtain and maintain additional task references just for memory access.
