arch: split MODULE_ARCH_VERMAGIC definitions out to

2020-04-23T01:50:26+00:00

As the bug report [1] pointed out, must be included after . I believe we should not impose any include order restriction. We often sort include directives alphabetically, but it is just coding style convention. Technically, we can include header files in any order by making every header self-contained. Currently, arch-specific MODULE_ARCH_VERMAGIC is defined in , which is not included from . Hence, the straight-forward fix-up would be as follows: |--- a/include/linux/vermagic.h |+++ b/include/linux/vermagic.h |@@ -1,5 +1,6 @@ | /* SPDX-License-Identifier: GPL-2.0 */ | #include |+#include | | /* Simply sanity version stamp for modules. */ | #ifdef CONFIG_SMP This works enough, but for further cleanups, I split MODULE_ARCH_VERMAGIC definitions into . With this, and will be orthogonal, and the location of MODULE_ARCH_VERMAGIC definitions will be consistent. For arc and ia64, MODULE_PROC_FAMILY is only used for defining MODULE_ARCH_VERMAGIC. I squashed it. For hexagon, nds32, and xtensa, I removed entirely because they contained nothing but MODULE_ARCH_VERMAGIC definition. Kbuild will automatically generate at build-time, wrapping .

ARC: module: Fix !CONFIG_ARC_DW2_UNWIND builds

2017-01-18T19:17:44+00:00

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

ARC: module: elide loop to save reference to .eh_frame

2016-10-28T17:10:28+00:00

The loop was really needed in .debug_frame regime where wanted make it as SH_ALLOC so that apply_relocate_add() would process it. That's not needed for .eh_frame, so we check this in apply_relocate_add() which gets called for each section. Note that we need to save reference to "section name strings" section in module_frob_arch_sections() since apply_relocate_add() doesn't get that Signed-off-by: Vineet Gupta
