 Log Message:
 cpuctl(8): decode L2 cache associativity for VIA CPUs using the AMD cache lookup
 table for the 0x80000006 CPUID function associativity value.
 
 Use `cpuid leaf 4' to get cache parameters for Zhaoxin and late VIA CPU models.
 
 Mirrors the changes from identcpu.c rev. 1.142.
 
 Additionally, use via_cpu_probe() and via_cpu_cacheinfo() for CPUVENDOR_IDT
 family > 6 CPUs to identify Zhaoxin CPUs and their features.
 Also, print feature 5-7 bits for CPUVENDOR_IDT, which appear to be compatible
 with Intel.
 
 Use vendorname = "Zhaoxin" for family 7 models.
 
 Tested on various 32-bit and 64-bit VIA and Zhaoxin CPUs
 (Samuel 2 / Nehemiah, Esther (32-bit), multiple Nano models, and KX-U6580/7000).
