In my view, these steps aren't sufficient, for the reasons described in 

http://marc.info/?l=linux-omap&m=135964568904053&w=2

Even with CONFIG_CPU_IDLE=n, it's still possible to attempt to enter 
full-chip retention idle on OMAP4 via 'echo mem > /sys/power/state', so it 
doesn't seem right to restrict a solution to that case.
