Subject: [PATCH] Generate <asm/asm-offsets.h> and remove identical copies in all architectures
Date: Mon, 18 May 2026 18:18:41 -0700 [thread overview]
Message-ID: <20260519011928.78398-1-enelsonmoore@gmail.com> (raw)
Every architecture supported by the kernel has a functionally identical
copy of <asm/asm-offsets.h> which simply includes
<generated/asm-offsets.h>, even though it is also present in
asm-generic. Eliminate this unnecessary complexity by adding
<asm/asm-offsets.h> to the list of mandatory asm headers, which causes
a copy of it that includes <asm-generic/asm-offsets.h> to be generated
automatically.
