This patch is only compile-tested for PowerPC and tested on ARM.
According to the datasheets for i.MX6 and P1010 this should be correct, though.

. On the other hand the sizeof(..)
solution would only catch little endian on 32bit and not big endian (?!)
I however don't know what combinations actually *have* to be caught, as I don't
know, which exist.
So, what do you think people?

Hi all!
I have a question regarding the use of the backlog in a driver
using the crypto API.
In my driver (crypto: sahara - SHA support) I had a problem with
using the backlog when I am using more than one thread to enqueue
the requests and have a queue depth of 1. What happens is, that I

:-( Okay
The driver uses a spinlock, but never initializes it.
