We've spent the last decade slowly moving away from platform-specific to generic multiplatform kernels on ARM (and, to a lesser extent, x86). I strongly disagree with adding a new flavour that would be specific to one vendor's platform. However, if it is possible to create a single flavour that provides those sorts of enhancements for multiple cloud platforms, I think that would be worthwhile. > We don't want to introduce a new source package as was done for > grsecurity.

Those are basically the same criteria we normally use, so I don't understand your desire to add a featureset. Ben. > Would it be okay with you if we try this?
