Dear Maintainer,

The Debian Bookworm i386 kernel configuration contains:

CONFIG_MGEODE_LX=y

in /boot/config-6.1.0-53-686.

For a generic 686 kernel, selecting the AMD Geode LX CPU target appears
incorrect. The -686 kernel should target the i686 baseline instead:

CONFIG_M686=y

CONFIG_MGEODE_LX is a very specific CPU target intended for AMD Geode GX/LX
processors, not a generic i686-compatible processor.

This choice may result in suboptimal CPU tuning for normal i686 hardware and
does not reflect the intended purpose of the -686 flavour.

Please consider changing the CPU configuration to CONFIG_M686=y or explain the
reason for selecting the Geode LX target in the generic 686 kernel flavour.

Geode was the chosen architecture base for Debian Bookworm.

May?  Please be specific what you mean.

This is for oldstable, we will not do changes to core configs in this
distribution.
