From eb1357d942e5d96de6b4c20a8ffa55acf96233a2 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Mon, 16 Jan 2017 10:48:09 -0800 Subject: ARC: module: Fix !CONFIG_ARC_DW2_UNWIND builds commit d65283f7b695b5 added mod->arch.secstr under CONFIG_ARC_DW2_UNWIND, but used it unconditionally which broke builds when the option was disabled. Fix that by adjusting the #ifdef guard. And while at it add a missing guard (for unwinder) in module.c as well Reported-by: Waldemar Brodkorb Cc: stable@vger.kernel.org #4.9 Fixes: d65283f7b695b5 ("ARC: module: elide loop to save reference to .eh_frame") Tested-by: Anton Kolesov Reviewed-by: Alexey Brodkin [abrodkin: provided fixlet to Kconfig per failure in allnoconfig build] Signed-off-by: Vineet Gupta --- arch/arc/kernel/module.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'arch/arc/kernel') diff --git a/arch/arc/kernel/module.c b/arch/arc/kernel/module.c index 42e964db2967..3d99a6091332 100644 --- a/arch/arc/kernel/module.c +++ b/arch/arc/kernel/module.c @@ -32,8 +32,8 @@ int module_frob_arch_sections(Elf_Ehdr *hdr, Elf_Shdr *sechdrs, #ifdef CONFIG_ARC_DW2_UNWIND mod->arch.unw_sec_idx = 0; mod->arch.unw_info = NULL; - mod->arch.secstr = secstr; #endif + mod->arch.secstr = secstr; return 0; } @@ -113,8 +113,10 @@ int apply_relocate_add(Elf32_Shdr *sechdrs, } +#ifdef CONFIG_ARC_DW2_UNWIND if (strcmp(module->arch.secstr+sechdrs[tgtsec].sh_name, ".eh_frame") == 0) module->arch.unw_sec_idx = tgtsec; +#endif return 0; -- cgit v1.2.3
