[PATCH 12/15] sparc: Remove AT_VECTOR_SIZE_ARCH from UAPI

From: Thomas Weißschuh

Date: Mon Mar 02 2026 - 07:32:42 EST


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.
