Pull kselftest updates from Shuah Khan:
 "This consists of:

   - Several fixes from Masami Hiramatsu to improve coverage for lib and

   - Clean up to vdso test and a new test for getcpu() from Mark Brown.

   - Add new gen_tar selftests Makefile target generate selftest package
     running "make gen_tar" in selftests directory from Veronika

Packaging selftests

===================



In some cases packaging is desired, such as when tests need to run on a

different system. To package selftests, run::



   $ make -C tools/testing/selftests gen_tar



This generates a tarball in the `INSTALL_PATH/kselftest-packages` directory. By

default, `.gz` format is used. The tar format can be overridden by specifying

a `FORMAT` make variable. Any value recognized by `tar's auto-compress`_ option

is supported, such as::



    $ make -C tools/testing/selftests gen_tar FORMAT=.xz



`make gen_tar` invokes `make install` so you can use it to package a subset of

tests by using variables specified in `Running a subset of selftests`_

section::



    $ make -C tools/testing/selftests gen_tar TARGETS="bpf" FORMAT=.xz



.. _tar's auto-compress: https://www.gnu.org/software/tar/manual/html_node/gzip.html#auto_002dcompress
