From: Dave Olson <[email protected]> Fix missing L2 cache size in /sys/devices/system/cpu/cpu0/cache/index2/size This bug appears to be introduced in 2.6.29 by 93197a36a9c16a85fb24cf5a8639f7bf9af838a3. The missing entry caused lscpu to error out on e500v2 devices, and probably others error: cannot open /sys/devices/system/cpu/cpu0/cache/index2/size: No such file or directory The DTS files we see use cache-size for the unified L2 cache size, not d-cache-size
