The patch titled
Subject: cpu-hotplug-smp-flush-any-pending-ipi-callbacks-before-cpu-offline-v3
has been removed from the -mm tree. Its filename was
cpu-hotplug-smp-flush-any-pending-ipi-callbacks-before-cpu-offline-v3.patch
This patch was dropped because it was folded into cpu-hotplug-smp-flush-any-pending-ipi-callbacks-before-cpu-offline.patch
------------------------------------------------------
From: Srivatsa S. Bhat <srivatsa.bhat@xxxxxxxxxxxxxxxxxx>
Subject: cpu-hotplug-smp-flush-any-pending-ipi-callbacks-before-cpu-offline-v3
Update: Move the switch-case handling for CPU_DYING such that
CPU_UP_CANCELED falls-through to CPU_DEAD (instead of CPU_DYING). Also,
add an explicit comment mentioning this.
