They're all independent, so please take the kvm ones via your tree. I can
send a separate pull if you prefer? Jason -- would you like an
irqchip-specific pull for those?

The only one I CC'd stable for was the compat ptrace watchpoint patch,
because that's something that we've been getting wrong and will cause
breakage with a 32-bit GDB. I don't consider the others urgent (i.e. happy
if you wait until 3.18).
