The association is relevant, as it is only a matter of time before a nasty kernel bug presents on Android devices. As the old kernels drift further from mainline, any effort to bring them up to speed becomes that much more difficult. Stagefright is an easy fix compared to a kernel issue.

There are all kinds of kernel bugs in every android release. That's just a simple fact. Most of root exploits are actually exploits of either the kernel or a privileged service running on top of it. We wouldn't be able to attain root without it.

Though better security would be a nice thing I doubt we'll see it unless the ARM phone chip guys embrace openness. Qualacom and others are openly hostile to openness.

AIUI, freedreno has received some patches from Qualcomm via their Innovation Center (iirc), on the drm side of things.

That was a lucky misunderstanding -- their bosses thought they were contributing to improvements in Digital Rights Management ;)
