If CPUs were the only reason, we could simply change those inlines and ENV_GET_CPU() macro to use a C cast. No complicated interface scenarios requiring a dynamic cast are used for CPUs so far to my knowledge. Either way, it would be nice to see the call sites of those most-impacting dynamic casts! So far I held back my APIC RFC since I'm not sure how to reproducibly profile things.
