Hi Niels,
My fault. I did not include the gym-aes-crypt.c in the patch. Here is the
updated patch. Please apply this one and we can work from there.
Thanks.

To Whom It May Concern,
This patch provides a performance improvement over AES/GCM with stitched
implementation for ppc64. The code is a wrapper in assembly to handle multiple
8 blocks and handle big and little endian.
The overall improvement is based on the nettle-benchmark with ~80%
