Yes, we now compile this code unconditionally and rely upon the linker to throw it away. Allegedly, this works.

I don't see anything in arch/i386/kernel/microcode.c depending on
CONFIG_HOTPLUG_CPU (in 2.6.20-rc1), sorry.

Re: [PATCH] microcode: Fix mc_cpu_notifier section warning
Hi Jean,
Ok, your patch is correct, although I assume you realize that it does
nothing --- both the function and the data it operates on are inside
CONFIG_HOTPLUG_CPU and checking include/linux/init.h I see that
__cpuinitdata is nothing in this case. E.g. msr_class_cpu_notifier in the
msr driver isn't declared __cpuinitdata...
But to tidy up one should add __cpuinitdata as you suggest (to guard for
the case if these two slip out of CONFIG_HOTPLUG_CPU, although they are
meaningless if cpu hotplug support is not configured in).
Kind regards
