With all alignment options set to 1 (minimum alignment),
I've got 5% smaller vmlinux compared to one built with
default code alignment.
It would be interesting to know if this is better WRT cache usage than
alignment which ensures that loops fit within the minimum number of
cache lines. That's not quite the same thing as starting on a cache line
in all cases.
This may be of interest to embedded builds.
