Since these extensions have some overlap in terms of register usage and must sometimes be tested together they're dropped into a single directory. I've adapted some of the tests to run within the kselftest framework but there are also some stress tests here that are intended to be run as soak tests so aren't suitable for running by default and are mostly just integrated with the build system. There doesn't seem to be a more suitable home for those stress tests and they are very useful for work on these areas of the code so it seems useful to have them somewhere in tree.
