From 5b7bdc4402b12bdad747cce305ecbc9737aed7ba Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Wei=C3=9Fschuh?= Date: Tue, 16 Sep 2025 18:51:35 +0200 Subject: [PATCH] kselftest/arm64/gcs/basic-gcs: Respect parent directory CFLAGS MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit basic-gcs has it's own make rule to handle the special compiler invocation to build against nolibc. This rule does not respect the $(CFLAGS) passed by the Makefile from the parent directory. However these $(CFLAGS) set up the include path to include the UAPI headers from the current kernel. Due to this the asm/hwcap.h header is used from the toolchain instead of the UAPI and the definition of HWCAP_GCS is not found. Restructure the rule for basic-gcs to respect the $(CFLAGS). Also drop those options which are already provided by $(CFLAGS).
