[kvm-unit-tests GIT PULL 02/11] s390x: lib: Move to GPL 2 and SPDX license identifiers

[Janosch Frank <frankja@linux.ibm.com>]

In the past we had some issues when developers wanted to use code
snippets or constants from the kernel in a test or in the library. To
remedy that the s390x maintainers decided to move all files to GPL 2
(if possible).

At the same time let's move to SPDX identifiers as they are much nicer
to read.
