Pull SPDX updates from Greg KH:
 "Here are some SPDX license marker changes.

  The SPDX-labeling effort has started to pick up again, so here are
  some changes for various parts of the tree that are related to this
  effort.

  Included in here are:

   - freevxfs license updates

   - spihash.c license cleanups

   - spdxcheck script updates to make things easier to work with going
     forward

  All of the license updates came from the original authors/copyright
  holders of the code involved.

  All of these have been in linux-next for weeks with no reported
  issues"
