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.
