[PATCH v3 0/2] arm: Replace __ASSEMBLY__ with __ASSEMBLER__ in uapi headers

[Thomas Huth]

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://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:

So please merge the arm patches via the arm tree. Thanks!

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, fixed the conflicts and new occurences
