Dear stable kernel maintainers, (Woah, two in one day; have I exceeded my limit?)

Please consider the attached patch for 5.4 and 4.19 for commit b8a9092330da ("Kbuild: do not emit debug info for assembly with LLVM_IAS=1"), which fixes a significant number of warnings under arch/ when assembling a kernel with Clang.

I also need a version of this for 5.9.y before we can take this for older kernels. Can you provide that as well?

Yes, apologies. It's similar to the 5.4.y patch, but with a shorter set of conflicts as noted in the commit message. Attached.
