Subject: [PATCH v2 09/13] sparc64: vdso2c: Drop sym_vvar_start handling
Date: Fri, 15 Aug 2025 12:41:18 +0200	[thread overview]
Message-ID: <20250815-vdso-sparc64-generic-2-v2-9-b5ff80672347@linutronix.de> (raw)
In-Reply-To: <20250815-vdso-sparc64-generic-2-v2-0-b5ff80672347@linutronix.de>

After the adoption of the generic vDSO library this symbol does not exist.

The alignment invariant is now guaranteed by the generic code.
