thats correct more often some patches whcih work on arm dont work on
other architectures so the patcheses we cherry pick usually exclude such
regressing patches and its a bit of work to identify them
but on positive side the patches we take get tested on wider
architectures. Also we only take gcc patches no other components

linaro layer would be a good idea although I think from distro point of
view they would want a single toolchain doing all architectures and
still would want advantages of linaro work so if this layer takes care
of fixing toolchain for non arm architectures it will be a lot of value
to distros using OE

but as such having layer would be a good thing as well.
