Matteo Croce ce71efd039 lib/test_string.c: allow module removal 
The test_string module can't be removed because it lacks an exit hook.
Since there is no reason for it to be permanent, add an empty one to allow
module removal.

Peter Rosin 33d6e0ff68 lib/test_string.c: avoid masking memset16/32/64 failures 
If a memsetXX implementation is completely broken and fails in the first
iteration, when i, j, and k are all zero, the failure is masked as zero
is returned.  Failing in the first iteration is perhaps the most likely
failure, so this makes the tests pretty much useless.  Avoid the
situation by always setting a random unused bit in the result on
failure.

Thomas Gleixner 09c434b8a0 treewide: Add SPDX license identifier for more missed files 
Add SPDX license identifiers to all files which:

 - Have no license information of any form

 - Have MODULE_LICENCE("GPL*") inside which was used in the initial
   scan/conversion to ignore the file

These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:

  GPL-2.0-only

Geert Uytterhoeven d6b28e0996 lib: add module support to string tests 
Extract the string test code into its own source file, to allow
compiling it either to a loadable module, or built into the kernel.
