patch 'common/cnxk: fix unaligned access to device memory' has been queued to stable release 21.11.2

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/30/22. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/d13786763aa466a972f57b0ff60d1739995ab5ca

Thanks.

Kevin

Subject: [PATCH] common/cnxk: fix unaligned access to device memory

[ upstream commit 6a65e22a4dad855fba1de4b793a208f2d6f12d5e ]

Use mbox_memcpy() instead of memcpy() to prevent unaligned access.
