Yes, I had forgotten at the time that we can run on 3.14 in the Cambridge
instance, which I rediscovered when writing this osstest patch:

        make-flight: Don't bother testing linux-3.10 on ARM.
        
        The earliest version which boots on the hardware in the colo is v3.16+
        from the current linux-arm-xen branch.
        
        However in the h/w in the Cambridge instance works ok with linux-3.14
        and linux-3.16.
        
        We already skip linux branches 3.4 and earlier, so just add 3.10 too.

Given the above failure I don't think the ability to test the 3.14 kernels
on the Cambridge instance is all that valuable. So yes, I think we should
drop ARM from the linux-3.14 flights.

We should also force push 3.14 if the above was the only failure.
