Subject: [PATCH v2 0/2] arm: Replace __ASSEMBLY__ with __ASSEMBLER__ in uapi headers
Date: Thu, 3 Jul 2025 19:38:57 +0200 [thread overview]
Message-ID: <20250703173859.246664-1-thuth@redhat.com> (raw)
The kernel Makefiles define the __ASSEMBLY__ macro to provide
a way to use headers in both, assembler and C source code.
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, it would make sense to standardize
on the macro that gets defined by the compiler, so this patch series
changes all occurances 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 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 I assume the arm patches should go via the arm tree.
v3:
- Split the arm patches from the global series
(see https://lore.kernel.org/all/20250314071013.1575167-1-thuth@redhat.com/)
- Rebased the patches on linux-next and fixed the conflicts
