[PATCH 0/4] PCI: Add support and tests for FIXUP quirks in modules

[Brian Norris]

This series primarily adds support for DECLARE_PCI_FIXUP_*() in modules.
There are a few drivers that already use this, and so they are
presumably broken when built as modules.

While at it, I wrote some unit tests that emulate a fake PCI device, and
let the PCI framework match/not-match its vendor/device IDs. This test
can be built into the kernel or built as a module.

I also include some infrastructure changes (patch 3 and 4), so that
ARCH=um (the default for kunit.py), ARCH=arm, and ARCH=arm64 will run
these tests by default. These patches have different maintainers and are
independent, so they can probably be picked up separately. I included
them because otherwise the tests in patch 2 aren't so easy to run.
