+From e7d24c0aa8e678f41457d1304e2091cac6fd1a2e Mon Sep 17 00:00:00 2001
+From: Ard Biesheuvel <[email protected]>
+Date: Thu, 28 Mar 2024 07:42:57 +0100
+Subject: gcc-plugins/stackleak: Avoid .head.text section
+
+The .head.text section carries the startup code that runs with the MMU
+off or with a translation of memory that deviates from the ordinary one.
+So avoid instrumentation with the stackleak plugin, which already avoids
+.init.text and .noinstr.text entirely.
+
+Fixes: 48204aba801f1b51 ("x86/sme: Move early SME kernel encryption handling into .head.text")
+Reported-by: kernel test robot <[email protected]>
+Closes: https://lore.kernel.org/oe-lkp/[email protected]
