Hey Denis,

I have already added one test case under selftests/powerpc/tm/ which
will test all the newly added ELF core note based ptrace requests on
powerpc. This test case is added as part of the next patch 8/8 in
the series. Please let me know if the test case does not cover something
you are looking for.
