Do we NOT want to have DEBUG_SLAB and DEBUG_PAGEALLOC both enabled?
Running multiple permutations is going to get really painful on the
systems involved. Any other requests for what gets enabled (I really
want to just stick to one 'debug' setup if possible).


Debug kernels are incredibly slow, making hitting certain races next to impossible. By all means non-DEBUG kernels should definately be getting tested.

It'd still run a totally non-debug kernel as well - I want that for the
perf tests etc anyway. I guess the question is whether the debug kernels
should have most of the DEBUG_* turned on, or just a select few.
