i believe the common cache line sizes are 64-bytes for most x86
machines, and 32-bytes for arms.

Yes, exactly my point. I read on Wiki that P4 had L2 with 128-byte lines, but I thought 64B is the most common. One can check individually around /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size
