For clarity, let's take your bullet-point list above as a list of
examples, and make that:

	/*
	 * As SYM_CODE functions don't follow the usual calling
	 * conventions, we assume by default that any SYM_CODE function
	 * cannot be unwound reliably.
	 *
	 * Note that this includes:
	 *
	 * - Exception handlers and entry assembly
	 * - Trampoline assembly (e.g., ftrace, kprobes)
	 * - Hypervisor-related assembly
	 * - Hibernation-related assembly
	 * - CPU start-stop, suspend-resume assembly
	 * - Kernel relocation assembly
	 */

This looks good to me too.
