Until we get these more reliable, you can assume that I'll flag
something that's really a blocker.

Only the exynos5422-odroidxu3 failure is a true failure which is also
happendin in mainline. It's been reported and fixed.

The others are silly lab/hardware issues that are hard to get
stabilized. e.g. QEMU taking a really long time to boot
CONFIG_PROVE_LOCKING=y kernels, flaky USB-UART cables etc.
