[PATCH v1 0/6] pseries/cpuidle: pseries cpuidle backend driver clean-ups.

[Deepthi Dharwar <deepthi@linux.vnet.ibm.com>]

The following patch series includes a bunch of clean-ups for the
pseries cpuidle backend driver. This includes,
moving the driver from arch/powerpc/platforms/pseries to
driver/cpuidle, refactoring of the code, making it a non-module,
removing smt-snooze-delay update and dead code around it.

After a number of attempts to consolidate the backend cpuidle driver 
for pSeries and powernv platforms, it seems best to have separate 
idle drivers for both the platforms as any kind of  code duplication 
seizes to exist beyond snooze loop and a hot plug notifier.  
Also going further, with addition of device tree parsing to setup
idle states and related changes just for powernv platform, it is
best to keep these drivers separate without adding complexity 
and thus improving readabilty for both the platform drivers.  

The clean-up undertaken here was posted earlier as part of
generic powerpc cpuidle driver clean-up.
