#     selftests/powerpc: Don't rely on segfault to rerun the test
#     
#     The test case tm-signal-context-force-tm expects a segfault to happen on
#     returning from signal handler, and then does a setcontext() to run the test
#     again. However, the test doesn't always segfault, causing the test to run a
#     single time.
#     
#     This patch fixes the test by putting it within a loop and jumping, via
#     setcontext, just prior to the loop in case it segfaults. This way we get the
#     desired behavior (run the test COUNT_MAX times) regardless if it segfaults or
#     not. This also reduces the use of setcontext for control flow logic, keeping it
#     only in the segfault handler.
#     
#     Also, since 'count' is changed within the signal handler, it is declared as
#     volatile to prevent any compiler optimization getting confused with
#     asynchronous changes.
