Subject: [PATCH 4/5] ARM: fix CPU_V6 dependencies
Date: Thu, 18 Aug 2022 16:56:15 +0200	[thread overview]
Message-ID: <20220818145616.3156379-5-arnd@kernel.org> (raw)
In-Reply-To: <20220818145616.3156379-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

CONFIG_XIP_KERNEL must not be combined with CONFIG_SMP_ON_UP
because the patching of read-only data does not work.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
