patch 'eal: cleanup alarm and hotplug before memory detach' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=0772cc1d89c8e74cd4ee09650676d1a23467039e

Thanks.

Subject: [PATCH] eal: cleanup alarm and hotplug before memory detach
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit cc75968228576250159918ec1531eecc606bc423 ]

Alarm and multiprocess hotplug still need access hugepage memory,
if alarm event processed after memory detach, it may cause SEGV.
So cleanup alarm and multiprocess hotplug before memory detach.

Fixes: 90b13ab8d4f7 ("alarm: remove direct access to interrupt handle")
Fixes: a0cc7be20dd1 ("mem: cleanup multiprocess resources")
