Subject: [PATCH v5 10/31] arm64: Prepare sharing arm64 headers with s390
Date: Fri, 31 Jul 2026 15:08:38 +0200	[thread overview]
Message-ID: <20260731130902.654679-11-seiden@linux.ibm.com> (raw)
In-Reply-To: <20260731130902.654679-1-seiden@linux.ibm.com>

Prepare the sharing of arm64 headers with s390 by moving a few
definitions inside headers to reduce the number of shared markers.
Clean up some includes to further streamline the sharing of headers.

No functional change.
