DSP (digital signal processors) let you manage cache yourself. And believe me, it isn't fun — it's something you'd want to do only for algorithms that merit tedious hand-tuning. As for linear, I believe the last high-performance CPU with a direct-mapped cache (e.g. not an X-way set associative one) was the DEC Alpha?
