Subject: [PATCH 08/17] x86/boot: Drop references to startup_64
Date: Fri, 18 Aug 2023 15:44:13 +0200 [thread overview]
Message-ID: <20230818134422.380032-9-ardb@kernel.org> (raw)
In-Reply-To: <20230818134422.380032-1-ardb@kernel.org>
The x86 boot image generation tool assign a default value to startup_64
and subsequently parses the actual value from zoffset.h but it never
actually uses the value anywhere. So remove this code.
