Hi,

> The suggested fix for #3759: [PATCH] crypto: use bigint in x86-64 perl addresses some issues but not all issues with the generation of the asm from the perl scripts.  Using the provided patch, one still fails with:

I can't reproduce the problem. And expected values in lines in question
are not big at all. What is common there is that there is division that
obviously mistreated on your system. Can you try/confirm if enclosing it
to backticks does the trick? I mean question is what happens if you
replace occurrences of 240/8 with `240/8`?
