+	* random.c (add_timer_randomness): Limit the amount randomness
+		that we estimate to 12 bits.  (An arbitrary amount).
+
+		(extract_entropy): To make it harder to analyze the hash
+		function, fold the hash function in half using XOR, and
+		use the folded result as the value to emit to the user.
+		Also, add timer randomness each pass through the
+		exact_entropy call, to increase the amount of unknown
+		values during the extraction process.
+
+		(random_ioctl): Use IOR/IOW definitions to define the
+		ioctl values used by the /dev/random driver.  Allow the
+		old ioctl values to be used for backwards compatibility
+		(for a limited amount of time).
