This series contains mainly fixes/improvements for cross-compilation (also verified on native platform build), tested on arm, but intended for any arch. Initial RFC link: https://lkml.org/lkml/2019/8/29/1665 Besides the pathces given here, the RFC also contains couple patches related to llvm clang arm: include: asm: swab: mask rev16 instruction for clang arm: include: asm: unified: mask .syntax unified for clang The change touches not only cross-compilation and can have impact on other archs and build environments, so might be good idea to verify it in order to add appropriate changes, some warn options could be tuned also.
