Subject: ftrace: add TRACE_STACK and TRACE_SPECIAL to selftest validation
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=06fa75ab566c50e01bfd7b055bde85cf9b1bc98a;p=mv-sheeva.git

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.
