Dear stable kernel maintainers, Our production kernel team and ChromeOS kernel teams are reporting that they are unable to symbolize addresses of symbols defined in assembly sources due to a regression I caused with commit a66049e2cf0e ("Kbuild: make DWARF version a choice")
I think you mean commit b8a9092330da ("Kbuild: do not emit debug info for assembly with LLVM_IAS=1"), which is what you blamed in 32ef9e5054ec? a66049e2cf0e does not appear to have any affect on this problem?
I fixed this upstream with commit 32ef9e5054ec ("Makefile.debug: re-enable debug info for .S files") but I think this is infeasible to backport through to 4.19.y.
Do the attached branch-specific variants look acceptable?
I think the stable specific versions should be okay. We should be able to deal with any fallout that happens if there is any.
