I've applied all but 'Revert "libata/ahci: accommodate tag ordered 
controllers"'. I'm pretty leery of reverting a stable upstream patch in 
order to accommodate early rev x-gene silicon. How about the approach 
suggested in (marc.info/?l=linux-kernel&m=140202343830821&w=2) ? That 
has the advantage of not affecting anything other then x-gene.

Is 'gpio: dwapb: drop irq_setup_generic_chip()' a candidate for 3.15 
stable ?
