#     selftests/powerpc: Add a signal fuzzer selftest
#     
#     This is a new selftest that raises SIGUSR1 signals and handles it in a
#     set of different ways, trying to create different scenario for testing
#     purpose.
#     
#     This test works raising a signal and calling sigreturn interleaved
#     with TM operations, as starting, suspending and terminating a
#     transaction. The test depends on random numbers, and, based on them,
#     it sets different TM states.
#     
#     Other than that, the test fills out the user context struct that is
#     passed to the sigreturn system call with random data, in order to make
#     sure that the signal handler syscall can handle different and invalid
#     states properly.
#     
#     This selftest has command line parameters to control what kind of
#     tests the user wants to run, as for example, if a transaction should
#     be started prior to signal being raised, or, after the signal being
#     raised and before the sigreturn. If no parameter is given, the default
#     is enabling all options.
#     
#     This test does not check if the user context is being read and set
#     properly by the kernel. Its purpose, at this time, is basically
#     guaranteeing that the kernel does not crash on invalid scenarios.
