From 41d194bf862d37c41af2a85f25000727bb8e5697 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Thu, 10 Sep 2026 12:39:45 +0200 Subject: [PATCH] EFI: don't use alias attribute for compat hypercall stubs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Recent Clang objects to types differing between alias and aliasee. Accept the unnecessary overhead and make the two compat stubs real functions.
