#     selftests/powerpc: Test for spurious kernel memory faults on radix
#     
#     Previously when mapping kernel memory on radix, no ptesync was
#     included which would periodically lead to unhandled spurious faults.
#     Mapping kernel memory is used when code patching with Strict RWX
#     enabled. As suggested by Chris Riedl, turning ftrace on and off does a
#     large amount of code patching so is a convenient way to see this kind
#     of fault.
#     
#     Add a selftest to try and trigger this kind of a spurious fault. It
#     tests for 30 seconds which is usually long enough for the issue to
#     show up.
