Peter Anvin" <hpa@...or.com> Cc: x86@...nel.org, linux-kernel@...r.kernel.org, Kees Cook <keescook@...omium.org>, Thomas Lendacky <Thomas.Lendacky@....com> Subject: [PATCH] x86/tools/relocs: Add _etext and __end_of_kernel_reserve to S_REL Pre-2.23 binutils makes symbols defined outside sections absolute, so these two symbols break the build on old linkers. Fixes: b907693883fd ("x86/vmlinux: Actually use _etext for the end of the text segment") Fixes: c603a309cc75 ("x86/mm: Identify the end of the kernel area to be reserved") Signed-off-by: Arvind Sankar <nivedita@...m.mit.edu> --- arch/x86/tools/relocs.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/x86/tools/relocs.c b/arch/x86/tools/relocs.c index ce7188cbdae5..0a6146d6414f 100644 --- a/arch/x86/tools/relocs.c +++ b/arch/x86/tools/relocs.c @@ -78,6 +78,8 @@ static const char * const sym_regex_kernel[S_NSYMTYPES] = { "__end_rodata_hpage_align|" #endif "__vvar_page|" + "_etext|" + "__end_of_kernel_reserve|" "_end)$" }; -- 2.24.1
