Local function references are disabled. The check_objcopy() function in scripts/recordmcount.pl is set up to parse GNU objcopy's version string, not llvm-objcopy's, which triggers the warning. Commit 799c43415442 ("kbuild: thin archives make default for all archs") made binutils 2.20 mandatory and commit ba64beb17493 ("kbuild: check the minimum assembler version in Kconfig") enforces this at configuration time so just remove check_objcopy() and $can_use_local instead, assuming --globalize-symbol is always available. llvm-objcopy has supported --globalize-symbol since LLVM 7.0.0 in 2018 and the minimum version for building the kernel with LLVM is 10.0.1 so there is no issue introduced: Link: https://github.com/llvm/llvm-project/commit/ee5be798dae30d5f9414b01f76ff807edbc881aa Link: https://lkml.kernel.org/r/20210802210307.3202472-1-nathan@kernel.org Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> Signed-off-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> 2021-07-18T18:10:30Z Linus Torvalds torvalds@linux-foundation.org 2021-07-18T18:10:30Z urn:sha1:6750691a82ad264dff140a7e9ca8f340729431f0 Pull Kbuild fixes from Masahiro Yamada: - Restore the original behavior of scripts/setlocalversion when LOCALVERSION is set to empty. - Show Kconfig prompts even for 'make -s' - Fix the combination of COFNIG_LTO_CLANG=y and CONFIG_MODVERSIONS=y for older GNU Make versions * tag 'kbuild-fixes-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: Documentation: Fix intiramfs script name Kbuild: lto: fix module versionings mismatch in GNU make 3.X kbuild: do not suppress Kconfig prompts for silent build scripts/setlocalversion: fix a bug when LOCALVERSION is empty 2021-07-18T14:48:14Z Lecopzer Chen lecopzer.chen@mediatek.com 2021-07-15T07:37:16Z urn:sha1:1d11053dc63094075bf9e4809fffd3bb5e72f9a6 When building modules(CONFIG_...=m), I found some of module versions are incorrect and set to 0. This can be found in build log for first clean build which shows WARNING: EXPORT symbol "XXXX" [drivers/XXX/XXX.ko] version generation failed, symbol will not be versioned. But in second build(incremental build), the WARNING disappeared and the module version becomes valid CRC and make someone who want to change modules without updating kernel image can't insert their modules. The problematic code is + $(foreach n, $(filter-out FORCE,$^), \ + $(if $(wildcard $(n).symversions), \ + ; cat $(n).symversions >> $@.symversions)) For example: rm -f fs/notify/built-in.a.symversions ; rm -f fs/notify/built-in.a; \ llvm-ar cDPrST fs/notify/built-in.a fs/notify/fsnotify.o \ fs/notify/notification.o fs/notify/group.o ... `foreach n` shows nothing to `cat` into $(n).symversions because `if $(wildcard $(n).symversions)` return nothing, but actually they do exist during this line was executed. -rw-r--r-- 1 root root 168580 Jun 13 19:10 fs/notify/fsnotify.o -rw-r--r-- 1 root root 111 Jun 13 19:10 fs/notify/fsnotify.o.symversions The reason is the $(n).symversions are generated at runtime, but Makefile wildcard function expends and checks the file exist or not during parsing the Makefile. Thus fix this by use `test` shell command to check the file existence in runtime. Rebase from both: 1. [https://lore.kernel.org/lkml/20210616080252.32046-1-lecopzer.chen@mediatek.com/] 2.

Unfortunately, it also changes behavior in a subtle way - if the user has empty "LOCALVERSION" variable, the plus sign is appended to the kernel version. It wasn't appended before. This patch reverts to the old behavior - we append the plus sign only if the LOCALVERSION variable is not set.
