tracepoint: Allow trace events in modules with TAINT_TEST
Commit 2852ca7fba9f ("panic: Taint kernel if tests are run")
introduced a new taint type, TAINT_TEST, to signal that an
in-kernel test module has been loaded.
TAINT_TEST taint type defaults into a 'bad_taint' list for
kernel tracing and blocks the creation of trace events. This
causes a problem for CXL testing where loading the cxl_test
module makes all CXL modules out-of-tree, blocking any trace
events.
Trace events are in development for CXL at the moment and this
issue was found in test with v6.0-rc1.
