Well, another way of looking at it is that one of the big goals people
have in funding Linaro is to get this sort of shared problem worked on.

There's a page in the elinux wiki that people have been using to track
some of this (intermittently it must be said):

   http://elinux.org/Kernel_areas_of_focus_for_mainlining

which focuses a lot on specific functionality rather than higher level
things and obviously internally people will look at their own pain
points.  There's things like big.LITTLE (the EAS work) and system wide
voltage and frequency scaling which are needed for competitive products
but aren't on there.
