[PATCH 1/3] selftests/ftrace: multiple_kprobes: Also check for support

[Thomas Meyer]

The multiple_kprobes test case fails to check for KPROBE_EVENT support.
Add the check to prevent a false test result.

[PATCH 2/3] selftests/intel_pstate: No need to compile test progs in the run script

[Thomas Meyer]

Both test programs are being compiled by make, so no need to compile both
programs in the runner script.
This resolves an error when installing all selftests via make install
and run them in a different environemnt.

Running tests in intel_pstate
========================================
./run.sh: line 35: gcc: command not found
Problem compiling aperf.c.

[PATCH 3/3] selftests/net: msg_zerocopy enable build with older kernel headers

[Thomas Meyer]

Explicitly define SO_EE_ORIGIN_ZEROCOPY.
This makes the test program build with older kernel headers,
e.g. from Debian 9.

Hi Steve/Masami,

This patch looks good to me. Adds a check similar to the one one in
tools/testing/selftests/ftrace/test.d/kprobe/functions

If you don't have objections, I will get this into 4.14-rc2 or rc3

thanks,
