Subject: [PATCH v3 01/10] x86/Kconfig: Geode CPU has cmpxchg8b
Date: Wed, 26 Feb 2025 22:37:05 +0100 [thread overview]
Message-ID: <20250226213714.4040853-2-arnd@kernel.org> (raw)
In-Reply-To: <20250226213714.4040853-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
An older cleanup of mine inadvertently removed geode-gx1 and geode-lx
from the list of CPUs that are known to support a working cmpxchg8b.
Fixes: 88a2b4edda3d ("x86/Kconfig: Rework CONFIG_X86_PAE dependency")
Cc: stable@vger.kernel.org
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
