Subject: [PATCH] ftrace: add TRACE_STACK and TRACE_SPECIAL to selftest
validation
The selftest validation code checks for valid entries in the trace buffer.
TRACE_STACK and TRACE_SPECIAL have been added to the code but not to
the validator. This patch adds the two to prevent them from flagging a
failure in the selftest.
