[PATCH 1/3] arm,tegra: replace cpu_set() with modern api

From: KOSAKI Motohiro <hidden>
Date: 2011-06-23 08:28:46

cpu_set() is marked as obsolete cpumask function and we plan to
remove it in future.

This patch replace it with modern cpumask function.

[PATCH 2/3] arm,integrator: replace old cpumask functions with new one.

From: KOSAKI Motohiro <hidden>
Date: 2011-06-23 08:31:04

We plant to change task->cpus_allowed implementation in future.
Therefore this patch replace it with tsk_cpus_allowed() helper
macro.
