Add Breno and Nayna as NX/VMX crypto driver maintainers. Also change my
email address to my personal account and remove Leonidas since he's not
working with the driver anymore.

Sure thing. I'll test it later today. Thanks Ondrej for the fix.

by the fact that ctr mode is using
blkcipher for the fallback.
I just sent a patch [1] to make it use skcipher and, since then, ipsec
with ikev2 and ghash are working fine for ppc64 and ppc64le.
Best regards,

In 2015, Andy Polyakov, the author, replied in this mailing list [1]:
"I have no problems with reusing assembly modules in kernel context. The
whole idea behind cryptogams initiative was exactly to reuse code in
different contexts."

Currently, neither cbc or xts are working with upstream kernel due to a failure
in the fallback allocation. This can be fixed by changing the fallback to
skcipher.
Paulo Flabiano Smorigo (2):
crypto: vmx - Use skcipher for cbc fallback
crypto: vmx - Use skcipher for xts fallback

ile.
Since generic is the only posible fallback for ppc, I think that's a
good solution. :)
