Subject: [PATCH 27/28] powerpc: Split systemcfg struct definitions out from vdso
Date: Thu, 10 Oct 2024 09:01:29 +0200	[thread overview]
Message-ID: <20241010-vdso-generic-base-v1-27-b64f0842d512@linutronix.de> (raw)
In-Reply-To: <20241010-vdso-generic-base-v1-0-b64f0842d512@linutronix.de>

The systemcfg data has nothing to do anymore with the vdso.
Split it into a dedicated header file.

Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
