This patch enables compression engine support in the
architecture vector. This causes the Power hypervisor
to allow access to the nx comrpession accelerator.

This is a continuation of a thread a few months ago:
https://lists.ozlabs.org/pipermail/linuxppc-dev/2012-February/095775.html
zsmalloc is now in the staging tree and there are patches
on lkml to convert the x86 only tlb flushing code to arch
independent code.
https://lkml.org/lkml/2012/5/14/55
When the nx driver was pulled, the Makefile that actually
builds it is arch/powerpc/Makefile. This is unnatural.
This patch moves the line that builds the nx driver from
arch/powerpc/Makefile to drivers/crypto/Makefile where it
belongs.

Seth,
Thanks for the help! I was wondering if you could take a look at something
for me.
I've been working on this staging driver (zsmalloc memory allocator)
that does virtual mapping of two pages.
I have a github repo with the driver and
) can provide would be appreciated!
Thanks,
Seth
