*Why* should it? Adding the L1 cache probably makes little or no difference
when the L2/L3 caches are usually so much larger (on my laptop, there's a
whole whopping 32K of L1, but 4M of L2 and no L3). It *might* make sense
to report L2+L3. It would depend on who uses that number, and for what.
But adding the trace cache is just batshit crazy.
