From f7cfe7017b531e08c108ac6615b1ddedcc892428 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Tue, 9 Jan 2024 09:22:32 +0100 Subject: [PATCH] x86/paravirt: Make BUG_func() usable by non-GPL modules Several inlined functions subject to paravirt patching are referencing BUG_func() after the recent switch to the alternative patching mechanism. As those functions can legally be used by non-GPL modules, BUG_func() must be usable by those modules, too. So use EXPORT_SYMBOL() when exporting BUG_func().
