These comments are from applying the patches to 5.0-rc3.

The final hunk of this patch fails to apply because it depends upon

[PATCH v1 0/1] of: unittest: unflatten device tree on UML when testing.

If I apply that patch then I can apply patches 15 through 17.

If I apply patches 1 through 14 and boot the uml kernel then the devicetree
unittest result is:

### dt-test ### FAIL of_unittest_overlay_high_level():2372 overlay_base_root not initialized
### dt-test ### end of unittest - 219 passed, 1 failed

This is as expected from your previous reports, and is fixed after
applying

[PATCH v1 0/1] of: unittest: unflatten device tree on UML when testing.

with the devicetree unittest result of:

### dt-test ### end of unittest - 224 passed, 0 failed

After adding patch 15, there are a lot of "unittest internal error" messages.
