It seems you still haven't received a response. I'll take a stab at this.

I think it fixes:

Fixes: 76746eb13f08 ("eal/x86: fix strict aliasing rules")

However, the ordering of the ifs (from 1 to 8, rather than 8 to 1)
seems to date back to the first commit (af75078fece3). So, I'm not
sure how you want to handle this.

Thanks.
