Btw, not sure if any of you have seen the 0-day kbuild setup that intel has..

runs various builds for different archs on every commit with different configs, randconfig, etc. And various checks with sparse, smatch, etc. Seems kinda useful, and would be a worthwhile goal to get arm arch to the point of "it just compiles and boots" like x86 is, vs arm which has a lot higher tendency to be broken if you don't have the right kernel config, etc. I guess on x86, they boot test all the kernels too on VMs. Perhaps we could go one better with something tied in to lava?
+1 on this, Rob.
Just about every time I go to bump kernel revisions for the linaro.android tree, and actually try to build and boot on a board, I regularly hit compile and boot issues.
Although for the boot issues, there's still the hard problem for hardware-simpletons like me in being able to figure out what configs I actually need to enable (especially as those options change over time). I suspect these sorts of problems are unlikely to be something we can test away, and instead need a more critical eye as to how the kconfig options are added (so there's less of a random set of options that you have to pick the right combination, and more of the existing physical dependencies being properly stating in the kconfig - but I realize this is more complicated to do then say).
