Subject: [PATCH 09/15] s390: Remove AT_VECTOR_SIZE_ARCH from UAPI
Date: Mon, 02 Mar 2026 13:25:33 +0100	[thread overview]
Message-ID: <20260302-at-vector-size-arch-v1-9-a11f03ba2ca8@linutronix.de> (raw)
In-Reply-To: <20260302-at-vector-size-arch-v1-0-a11f03ba2ca8@linutronix.de>

There is nothing userspace can do with this value. In the kernel is
always combined with AT_VECTOR_SIZE_BASE, which is not exposed to
userspace and also changes from time to time.

Move the symbol to a kernel-internal header.
