Currently the cpuidle drivers are spread across the different archs.
The patch submission for cpuidle are following different path: the cpuidle core code goes to linux-pm, the ARM drivers goes to arm-soc or the SoC specific tree, sh goes through sh arch tree, pseries goes through PowerPC and finally intel goes through Len's tree while acpi_idle goes under linux-pm.
That makes difficult to consolidate the code and to propagate modifications from the cpuidle core to the different drivers.
Hopefully, a movement has initiated to put the cpuidle drivers into the drivers/cpuidle directory like cpuidle-calxeda.c and cpuidle-kirkwood.c
Add an explicit maintainer entry in the MAINTAINER to clarify the situation and prevent new cpuidle drivers to goes to an arch directory.
The upstreaming process is unchanged: Rafael takes the patches to merge them into its tree but with the acked-by from the driver's maintainer. So the header must contains the name of the maintainer.
This organization will be the same than cpufreq.
