You can probably work around it by enabling ARCH_HIGHBANK,
which is a minimal platform with no other requirements, so it
should only add a few milliseconds to the build.
Another option would be to do the testing on top of linux-next,
which should have your fix starting on Monday. Testing on
linux-next carries a higher risk of running into unrelated
regressions, but also lets you find out about conflicts with
other patches early on.
