From: Eric Biggers <ebigg...@google.com>
As discussed in the thread containing
https://lore.kernel.org/linux-crypto/20250510053308.GB505731@sol/, the
Power10-optimized Poly1305 code is currently not safe to call in softirq
context. Disable it for now. It can be re-enabled once it is fixed.
Fixes: ba8f8624fde2 ("crypto: poly1305-p10 - Glue code for optmized Poly1305
implementation for ppc64le")
