+From b6f9b3f6fa782807c4a7ec16ee8ef868cdfbf468 Mon Sep 17 00:00:00 2001
+From: Naveen Saini <naveen.kumar.saini@intel.com>
+Date: Mon, 15 Mar 2021 14:56:18 +0800
+Subject: [PATCH] The output in moddep.lst generated from syminfo.lst using
+ genmoddep.awk is not deterministic since the order of the dependencies on
+ each line can vary depending on how awk sorts the values in the array.
+
+Be deterministic in the output by sorting the dependencies on each line.
+
+Also, the output of the SOURCES lines in grub-core/Makefile.core.am, generated
+from grub-core/Makefile.core.def with gentpl.py is not deterministic due to
+missing sorting of the list used to generate it. Add such a sort.
+
+Also ensure the generated unidata.c file is deterministic by sorting the
+keys of the dict.
