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.

Applied (with modified changelog).
One consequence of this is that I'll be asking you to ACK changes in ARM cpuidle drivers. :-)
Thanks, Rafael
