From 3df8585afd9b340dc789b20f1101593961fc7e9e Mon Sep 17 00:00:00 2001 From: Thomas Weissschuh Date: Tue, 3 Feb 2026 08:11:48 +0100 Subject: [PATCH] ARM: 9469/1: Implement ARCH_HAS_CC_CAN_LINK MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The generic CC_CAN_LINK detection does not handle different byte orders. This may lead to userprogs which are not actually runnable on the target kernel. Use architecture-specific logic supporting byte orders instead.
