patch 'common/cnxk: fix mbox struct attributes' has been queued to stable release 21.11.7

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/13/24. 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/22c015d09d61a6d70101fc3cbf68a3a99adefa46

Thanks.

Kevin

Subject: [PATCH] common/cnxk: fix mbox struct attributes

[ upstream commit c9dca1c5e352008bda8d0edeab8fbcf328437282 ]

IO attribute is needed to mbox structs to avoid unaligned or pair
access causing by compiler optimization. Add them to structs
where it is missing.

Fixes: 503b82de2cbf ("common/cnxk: add mbox request and response definitions")
Fixes: ddf955d3917e ("common/cnxk: support CPT second pass")
