Pull Kselftest fixes from Shuah Khan:
 "Fixes for existing tests and the framework.

  Cristian Marussi's patches add the ability to skip targets (tests) and
  exclude tests that didn't build from run-list. These patches improve
  the Kselftest results. Ability to skip targets helps avoid running
  tests that aren't supported in certain environments. As an example,
  bpf tests from mainline aren't supported on stable kernels and have
  dependency on bleeding edge llvm. Being able to skip bpf on systems
  that can't meet this llvm dependency will be helpful.

  Kselftest can be built and installed from the main Makefile. This
  change help simplify Kselftest use-cases which addresses request from
  users.

  Kees Cook added per test timeout support to limit individual test
  run-time"

@@ -89,6 +89,22 @@ To build, save output files in a separate directory with KBUILD_OUTPUT ::
$ export KBUILD_OUTPUT=/tmp/kselftest; make TARGETS="size timers" kselftest
Additionally you can use the "SKIP_TARGETS" variable on the make command
line to specify one or more targets to exclude from the TARGETS list.
To run all tests but a single subsystem::
$ make -C tools/testing/selftests SKIP_TARGETS=ptrace run_tests
You can specify multiple tests to skip::
$ make SKIP_TARGETS="size timers" kselftest
You can also specify a restricted list of tests to run together with a
dedicated skiplist::
$ make TARGETS="bpf breakpoints size timers" SKIP_TARGETS=bpf kselftest
See the top-level tools/testing/selftests/Makefile for the list of all
possible targets.
