+From 63a3f603413ffe82ad775f2d62a5afff87fd94a0 Mon Sep 17 00:00:00 2001
+From: "H. Peter Anvin" <hpa@linux.intel.com>
+Date: Thu, 7 Feb 2013 17:14:08 -0800
+Subject: [PATCH] timeconst.pl: Eliminate Perl warning
+
+defined(@array) is deprecated in Perl and gives off a warning.
+Restructure the code to remove that warning.
+
+[ hpa: it would be interesting to revert to the timeconst.bc script.
+  It appears that the failures reported by akpm during testing of
+  that script was due to a known broken version of make, not a problem
+  with bc.  The Makefile rules could probably be restructured to avoid
+  the make bug, or it is probably old enough that it doesn't matter. ]
