Merge tag 'linux-kselftest-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull Kselftest update from Shuah Khan:

- Work to restructure timers test suite to move PIE out of rtctest from
Alexandre Belloni.

- Several minor spelling and bug fixes.

- New cgroup tests from Roman Gushchin and Mike Rapoport.

- Kselftest framework changes to handle and report skipped tests
correctly.

Prior to these changes, framework treated all non-zero return codes
from tests as failures. When tests are skipped with non-zero return
code, due to unmet dependencies and/or unsupported configuration,
reporting them as failed lead to false negatives on the tests that
couldn't be run.

- Fixes to test Makefiles to remove unnecessary RUN_TESTS and
EMIT_TESTS overrides and use common defines from lib.mk.

- Fixes to several tests to return correct Kselftest skip code.

- Changes to improve test output.

selftests: firmware: return Kselftest Skip code for skipped tests

When firmware test(s) get skipped because of unmet dependencies and/or
unsupported configuration, it returns 0 which is treated as a pass
by the Kselftest framework. This leads to false positive result even
when the test could not be run.

Change it to return kselftest skip code when a test gets skipped to
clearly report that the test could not be run.

Kselftest framework SKIP code is 4 and the framework prints appropriate
messages to indicate that the test is skipped.

"Here is the "big" set of driver core patches for 4.17-rc1.

There's really not much here, just a bunch of firmware code
refactoring from Luis as he attempts to wrangle that codebase into
something that is managable, along with a bunch of userspace tests for
it. Other than that, a handful of small bugfixes and reverts of things
that didn't work out.

Full details are in the shortlog, it's not all that much.

All of these have been in linux-next for a while with no reported

test_firmware: modify custom fallback tests to use unique files

Users of the custom firmware fallback interface is are not supposed to
use the firmware cache interface, this can happen if for instance the
one of the APIs which use the firmware cache is used first with one
firmware file and then the request_firmware_nowait(uevent=false) API
is used with the same file.

We'll soon become strict about this on the firmware interface to reject
such calls later, so correct the test scripts to avoid such uses as well.
We address this on the tests scripts by simply using unique names when
testing the custom fallback interface.

test_firmware: enable custom fallback testing on limited kernel configs

When a kernel is not built with:

CONFIG_HAS_FW_LOADER_USER_HELPER_FALLBACK=y

We don't currently enable testing fw_fallback.sh. For kernels that
still enable the fallback mechanism, its possible to use the async
request firmware API call request_firmware_nowait() using the custom
interface to use the fallback mechanism, so we should be able to test
this but we currently cannot.

We can enable testing without CONFIG_HAS_FW_LOADER_USER_HELPER_FALLBACK=y
by relying on /proc/config.gz (CONFIG_IKCONFIG_PROC), if present. If you
don't have this we'll have no option but to rely on old heuristics for now.

We stuff the new kconfig_has() helper into our shared library as we'll
later expando on its use elsewhere.
