I wouldn't expect most population to build their own kernels on
tablets/phones. And even if you could install a custom kernel, mainline
rarely runs on such devices because of tons of out of tree patches (just
look at the Nexus 9 patches that Kumar pointed at; even ignoring the
booting protocol they are extremely far from an upstreamable form).
