Hi Ard,
Thanks a lot for taking the time to double check this. I think it
would be nice to be able to expose xchacha12 like we do on other
architectures.
Note that for xchacha, I also added a hchacha_block() routine based on
your code (with the round count as the thi

Please benchmark it to indicate that,

Please benchmark it to indicate that, if it really isn't a big deal. I

This integrates the accelerated MIPS 32r2 implementation of ChaCha
into both the API and library interfaces of the kernel crypto stack.
The significance of this is that, in addition to becoming available
as an accelerated library implementation, it can also be used by
existing crypto API code such
