I see that you used the same commit message and title for many patches,
it will be better to have description on what exactly you are removing
and why there is no bug in that code.
Thank you for the suggestion.
I will add a note saying that it is up to the maintainer to verify
whether the code is applicable or not.
The intention of the patch is to point out a duplication of code found
by a Coccinelle script. I'm also working on similar issues reported by
Coverity. It was tested only by compilation as I don't have the proper
hardware to test it on.

You should remove be64_gt() too.
Thank you for pointing it out.
