The patch titled
change the 'no_control' field to 'hotpluggable' in the struct cpu
has been removed from the -mm tree. Its filename was
i386-introduce-the-mechanism-of-disabling-cpu-hotplug-control-cleanup.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: change the 'no_control' field to 'hotpluggable' in the struct cpu
From: "Siddha, Suresh B" <suresh.b.siddha@xxxxxxxxx>
Change the 'no_control' field in the cpu struct to a more positive
and better term 'hotpluggable'. And change(/cleanup) the logic accordingly.
