This patch adds the driver for interacting with the 842 compression accelerator on IBM Power7+ systems. The device is a child of the Platform Facilities Option (PFO) and shows up as a child of the IBM VIO bus. The compression/decompression API takes the same arguments as existing compression methods like lzo and deflate. The 842 hardware operates on 4K hardware pages and the driver breaks up input on 4K boundaries to submit it to the hardware accelerator.
