entirely up to you as long as they demonstrate REMAP capability rather than
are a bland superficial SIMD-i-fi-cation of existing tired (not a spelling
mistake) methods of doing either algorithm

yes this means pulling out the stops and getting ed25529 bigmul powmd
*and the associated REMAP engines completed before FOSDEM*.

which should help you to appreciate why i said to work as fast as you can
to get off of mmap as fast as possible as there is a HELL of a lot to get
done and none of it can be dropped.
