From 80c4e1948908f725564997c78d10110d9b21a015 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Wei=C3=9Fschuh?= Date: Thu, 21 Aug 2025 09:56:45 +0200 Subject: [PATCH] arm64: vdso32: Stop suppressing warnings MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit These warnings don't seem to trigger anymore. Probably due to the introduction of the vdso/ header namespace. Nowadays these suppression only hide real problems. Re-enable the warnings.
