New Linux Kernel Code Works On APIC "Decrapification", Suggests Dropping x86 32-bit

There's a lovely new Linux kernel patch series out that's big in working on a major clean-up of the x86 APIC code (or "decrapification" as it's called in the patches) and also bringing up for discussion the idea of killing off x86 32-bit support. It's unlikely the x86 32-bit support will be removed right now, which is "just museum pieces", but as an alternative would be making it SMP-only to at least remove the uni-processor code paths...
