Let's forget you sent this email, so you can start over and:
- work on your tone; I find it hard to care about what *you* need if
you don't take the time to introduce yourself, explain what you are
trying to accomplish, for what purpose and how and to which extent
that purpose aligns with that of our community
- think carefully about what validation of a crypto algorithm
implementation means, and whether it makes sense to do it in an arm64
specific way
- familiarize yourself with the way crypto code is checked for
correctness before it gets merged by Herbert (hint: it is related to
the dirty test module)
- assuming that you are working on Xgene, find out which algorithms in
arm64/crypto can even run on that chip, as it does not have the Crypto
Extensions
- get rid of the legalese footer, it has no place on an open source mailing list

Regards,
Ard.
