Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit ac7c3e4ff401b304489a031938dbeaab585bfe0a Author: Masahiro Yamada AuthorDate: Wed Sep 25 16:47:42 2019 -0700 Commit: Linus Torvalds CommitDate: Wed Sep 25 17:51:40 2019 -0700 compiler: enable CONFIG_OPTIMIZE_INLINING forcibly Commit 9012d011660e ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING") allowed all architectures to enable this option. A couple of build errors were reported by randconfig, but all of them have been ironed out. Towards the goal of removing CONFIG_OPTIMIZE_INLINING entirely (and it will simplify the 'inline' macro in compiler_types.h), this commit changes it to always-on option. Going forward, the compiler will always be allowed to not inline functions marked 'inline'. This is not a problem for x86 since it has been long used by arch/x86/configs/{x86_64,i386}_defconfig. I am keeping the config option just in case any problem crops up for other architectures. The code clean-up will be done after confirming this is solid.
