Subject: RFD: Does CONFIG_X86_LOCAL_APIC still make sense?

I'm trying to wrap my head around if there are use cases where disabling
either CONFIG_X86_UP_APIC or CONFIG_X86_LOCAL_APIC would ever make sense
anymore.

I am guessing there are probably some small number of embedded systems
which still don't have LAPICs, but is it a significant number and does
anyone care for new kernels?  We are not talking about discontinuing
support for non-APIC configurations, just the configuration option.
