Currently, cpu_online_cores_map returns a mask, which for every core
that has atleast one online thread, has the first-cpu-of-that-core's bit
set. But the first cpu itself may not be online always. In such cases, if
the returned mask is used for IPI, then it'll cause IPIs to be skipped
on cores whe
This is a cleanup patch; doesn't change any functionality. Moves
all cpuidle related code from setup.c to a new file.

Fastsleep is one of the idle state which cpuidle subsystem currently
uses on power8 machines. In this state L2 cache is brought down to a
threshold voltage. Therefore when the core is in fastsleep, the
communication between L2 and L3 needs to be fenced. But there is a bug
in the current power8 chip
