[PATCH] objtool: Replace __ASSEMBLY__ with __ASSEMBLER__ in header files

From: Thomas Huth

Date: Fri Jun 19 2026 - 12:05:57 EST


From: Thomas Huth <thuth@xxxxxxxxxx>

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).

mine to ease reviewing.
