This is a continuation of support for the Power7+ in-Nest
hardware accelerator.

https://lkml.org/lkml/2012/4/12/223

This patchset adds the hardware driver and the cryptographic
driver for hardware accelerated compression, which uses a
hardware-optimized algorithm named 842.

The hardware driver has limits on generic compression and is
geared toward compressing units that are of PAGE_SIZE for
in-kernel memory compression.

Based on linux-next (20120717)

Seth Jennings (4):
  powerpc: nx: rework Kconfig
  powerpc: nx: add compression support to arch vec
  powerpc: nx: add 842 hardware compression driver
  crypto: add 842 crypto driver

All applied.  Thanks Seth.
