------------------------------------------------------
Subject: suspend: don't change cpus_allowed for task initiating the suspend
From: "Siddha, Suresh B" <suresh.b.siddha@xxxxxxxxx>
Don't modify the cpus_allowed of the task initiating the suspend.
_cpu_down() already makes sure that the task doing the suspend doesn't run
on dying cpu.
