+ percpu-replace-__assembly__-with-__assembler__-in-percpu-defsh-header-file.patch added to mm-new branch

[Andrew Morton <akpm@linux-foundation.org>]

The patch titled
     Subject: percpu: replace __ASSEMBLY__ with __ASSEMBLER__ in percpu-defs.h header file
has been added to the -mm mm-new branch.  Its filename is
     percpu-replace-__assembly__-with-__assembler__-in-percpu-defsh-header-file.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/percpu-replace-__assembly__-with-__assembler__-in-percpu-defsh-header-file.patch

This patch will later appear in the mm-new branch at
    git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews.  Please do not hesitate to respond to
review feedback and post updated versions to replace or incrementally
fixup patches in mm-new.

The mm-new branch of mm.git is not included in linux-next

If a few days of testing in mm-new is successful, the patch will me moved
into mm.git's mm-unstable branch, which is included in linux-next

Before you just go and hit "reply", please:
   a) Consider who else should be cc'ed
   b) Prefer to cc a suitable mailing list as well
   c) Ideally: find the original patch on the mailing list and do a
      reply-to-all to that, adding suitable additional cc's

*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***

The -mm tree is included into linux-next via various
branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
and is updated there most days

Subject: percpu: replace __ASSEMBLY__ with __ASSEMBLER__ in percpu-defs.h header file
Date: Fri, 19 Jun 2026 17:47:04 +0200

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a macro that
only gets defined by the Makefiles in the kernel.  This can be very
confusing when switching between userspace and kernelspace coding, or when
dealing with uapi headers that rather should use __ASSEMBLER__ instead. 
So let's standardize now on the __ASSEMBLER__ macro that is provided by
the compilers.

This is a completely mechanical patch (done with a simple "sed -i"
statement.
