Subject: [PATCH 5/7] x86: remove dependencies on CONFIG_M... CPU options
Date: Thu, 5 Nov 2026 17:34:36 +0100 [thread overview]
Message-ID: <20261105163440.2381661-6-arnd@kernel.org> (raw)
In-Reply-To: <20261105163440.2381661-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
CPU specific features should generally be controlled by
CPU_SUP_xxx options rather than CONFIG_Mxxx, to allow
generic kernels to be built that work with all of them.
Replace the few options that don't follow this scheme
with checks on either CPU_SUP_xxx or X86_PAE by itself.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
