And really: Wasting 1/3 of the 80 character line is too much.

You _WASTE_ 4 chars only if you are interested in this info by
enabling: CONFIG_PRINTK_CPUID

I guess you waste 4 + 3 chars? You could optimize the length by checking
CONFIG_NR_CPUS?

Good point.
Looks there is a variable 'nr_cpu_ids' that could be used as well.

If there is general consensus that the patch can help the arm
community, and others in general,
this optimization should be easy to implement - saving few chars space
in each line of console output.

For now i will stick to this v3 version of path, unless you think otherwise.
