Check if ipg clock is in clock-names property, then we can move the
ipg clock enable and disable operation to startup and shutdown, that
is only enable ipg clock when ssi is working and keep clock is disabled
when ssi is in idle.
But when the checking is failed, remain the clock control as before.

Today the procfs interface /proc/sys/kernel/powersave-nap is used to control
entry into deep idle states beyond snooze. Check for the value of this
parameter before entering fastsleep. We already do this check for nap in
power7_idle().

Currently in the event of a stack overrun a call to schedule()
does not check for this type of corruption. This corruption is
often silent and can go unnoticed. However once the corrupted
region is examined at a later stage, the outcome is undefined
and often results in a sporadic page fault which
This facility is used in a few places so let's introduce
a helper function to improve code readability.

Tasks get their end of stack set to STACK_END_MAGIC with the
aim to catch stack overruns. Currently this feature does not
apply to init_task. This patch removes this restriction.
Note that a similar patch was posted by Prarit Bhargava [1]
some time ago but was never merged.

These values need to be converted when used by little endian
