From 537da1ed54658e916141e50923a7f5b20c728856 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 8 Mar 2022 16:30:15 +0100 Subject: [PATCH] objtool,efi: Update __efi64_thunk annotation The current annotation relies on not running objtool on the file; this won't work when running objtool on vmlinux.o. Instead explicitly mark __efi64_thunk() to be ignored. This preserves the status quo, which is somewhat unfortunate. Luckily this code is hardly ever used.
