Again, your patch description is not sufficient.
Also, nobody uses this function, so why add it?
Finally, if you add it, you will have to add it for all architectures.
Best regards,

I have nothing much to say about it.
Also, nobody uses this function, so why add it?
I think I am using it in the stratix.c file which is part of the stratix patch.. but I Will recheck
Finally, if you add it, you will have to add it for all architectures.
agreed.
