Use the vector polynomial multiply-sum instructions in POWER8 to speed up crc32c. This is just over 41x faster than the slice-by-8 method that it replaces. Measurements on a 4.1 GHz POWER8 show it sustaining 52 GiB/sec. A simple btrfs write performance test: dd if=/dev/zero of=/mnt/tmpfile bs=1M count=4096 sync is over 3.7x faster.
