Pull squashfs update from Phillip Lougher:
 "These patches optionally add LZ4 compression support to Squashfs.

  LZ4 is a lightweight compression algorithm which can be used on
  embedded systems to reduce CPU and memory overhead (in comparison to
  the standard zlib compression).

  These patches add the wrapper code to allow Squashfs to use the
  existing LZ4 decompression code, and the necessary configuration
  option"
