└─>Cache Line Length (as power of 2)
In linux kernel since version 3.1 (release Date: 2011-10-24)
Starting with ARC700 4.9, Cache line length is configurable,
This option specifies "N", with Line-len = 2 power N
So line lengths of 32, 64, 128 are specified by 5,6,7, respectively
Linux only supports same line lengths for I and D caches.
