Arch maintainers, please ack/review patches.
This is a resend of a series from Frank last year[1]. I worked in Rob's
review comments to unconditionally call unflatten_device_tree() and
fixup/audit calls to of_have_populated_dt() so that behavior doesn't
change.
I need this series so I can add DT based tests in the clk framework.
Either I can merge it through the clk tree once everyone is happy, or
Rob can merge it through the DT tree and provide some branch so I can
base clk patches on it.
Changes from Frank's series[1]:
* Add a DTB loaded kunit test
* Make of_have_populated_dt() return false if the DTB isn't from the
bootloader
* Architecture calls made unconditional so that a root node is always
made
Frank Rowand (2):
of: Create of_root if no dtb provided by firmware
of: unittest: treat missing of_root as error instead of fixing up
Stephen Boyd (4):
arm64: Unconditionally call unflatten_device_tree()
um: Unconditionally call unflatten_device_tree()
of: Always unflatten in unflatten_and_copy_device_tree()
of: Add KUnit test to confirm DTB is loaded

Currently the seccomp benchmark selftest produces non-standard output,
meaning that while it makes a number of checks of the performance it
observes this has to be parsed by humans. This means that automated
systems running this suite of tests are almost certainly ignoring the
results which isn't ideal for spotting problems. Let's rework things so
that each check that the program does is reported as a test result to
the framework.

Add missing tests to run_vmtests.sh. The mm kselftests are run through
run_vmtests.sh. If a test isn't present in this script, it'll not run
with run_tests or `make -C tools/testing/selftests/mm run_tests`.
