Hi Shua,

Here is the set with cleanup as suggested by Kees on v3.

Configured, built, and tested all modules loaded by
tools/testing/selftests/lib/*.sh

From previous cover letters ...

While doing the testing for strscpy_pad() it was noticed that there is
duplication in how test modules are being fed to kselftest and also in
the test modules themselves.

This set makes an attempt at adding a framework to kselftest for writing
kernel test modules.  It also adds a script for use in creating script
test runners for kselftest.  My macro-foo is not great, all criticism
and suggestions very much appreciated.  The design is based on test
modules lib/test_printf.c, lib/test_bitmap.c, lib/test_xarray.c.

Changes since last version:

 - Remove dependency on Bash (thanks Kees)
 - Use oneliner to implement kselftest test runners (thanks Kees)
 - Squash patch that adds kselftest script creator script with patch
   that uses it. 
 - Fix typos (thanks Randy)
 - Add Kees' Acked-by tags to all patches

thanks,
Tobin.
