In linux kernel since version 5.1 (release Date: 2019-05-05)
There are cases that a commit from one domain changes the function
address alignment of other domains, and cause magic performance
bump (regression or improvement). Enable this option will help to
verify if the bump is caused by function alignment changes, while
it will slightly increase the kernel size and affect icache usage.
It is mainly for debug and performance tuning use.
