However, all the supported versions of the GCC and Clang compilers also define the macro __ASSEMBLER__ automatically already when compiling assembly code, so some kernel headers are using __ASSEMBLER__ instead. With regards to userspace code, this seems also to be constant source of confusion, see for example these links here: https://lore.kernel.org/kvm/20250222014526.2302653-1-seanjc@google.com/ https://stackoverflow.com/questions/28924355/gcc-assembler-preprocessor-not-compatible-with-standard-headers https://forums.raspberrypi.com/viewtopic.php?p=1652944#p1653834 https://github.com/riscv-software-src/opensbi/issues/199 To avoid confusion in the future, we should standardize on the macro that gets defined by the compiler, so this patch series changes all occurences of __ASSEMBLY__ into __ASSEMBLER__. I split the patches per architecture to ease the review, and I also split the uapi headers from the normal ones in case we decide that uapi needs to be treated differently from the normal headers here. The related cleanup patches for e.g. x86, parisc, sh and arc patches already got merged via their specific architecture tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=24a295e4ef1ca8 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8a141be3233af7 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cccaea1d66e94b https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e2b6a188625a2b https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9cc646950eefda https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=179e949719fe81 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2cb74be378675c So please merge the arm patches via the arm tree.
