Elsewhere I've used CONFIG_ARCH_WANTS_NO_INSTR for this. Anyway, I took it for a spin and it .... doesn't seems to do the job. With my patch the first splat is "RCU not on for: cpuidle_poll_time+0x0/0x70" While with yours I seems to get the endless: "WARNING: suspicious RCU usage" thing. Let me see if I can figure out where it goes side-ways.
