From 4202f740038c9cfee57deacc99878b097d5cb16c Mon Sep 17 00:00:00 2001
From: Miod Vallat <miod@cvs.openbsd.org>

Subject: Rework the per-cpu cache information. Use a common struct to store
 the line size, the number of sets, and the total size (and the set size, for
 convenience) per cache (I$, D$, L2, L3). This allows cpu.c to print the
 number of ways (sets) of L2 and L3 caches from the cache information, rather
 than hardcoding this from the processor type.
