Subject: [PATCH 0/3] selftests/tracing: Fix some testcases for recent change

This includes some patches to fix 2 issues on ftrace selftests.

- eprobe filter and eprobe syntax test case were introduced but it
  doesn't check whether the kernel supports eprobe filter. Thus the
  new test case fails on the kernel which has eprobe but not support
  eprobe filter. To solve this issue, add a filter description to
  README file [1/3] and run the filter syntax error test only if the
  description is found in the README file [2/3].

- Recently objtool adds prefix symbols for the function padding nops,
  and the probepoint test case fails because this probepoint test case
  tests whether the kprobe event can probe the target function and the
  functions next to the target function. But the prefix symbols can not
  be probed. Thus these prefix symbols must be skipped [3/3].

Thank you,
