Hi,

FYI, your patch has been queued to stable release 24.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/22/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/edefd4b2caffa1151b756f075dbc50d3b17d196c

Thanks.

Luca Boccassi

Subject: [PATCH] rcu: fix build with MSVC

[ upstream commit d1ab1a2facf9b823bc400e573aa39381ca7b915f ]

Within GitHub actions, with MSVC 19.44.35219,
the following error can be reported:

...\rte_rcu_qsbr.h(566): error C2220:
	the following warning is treated as an error
...\rte_rcu_qsbr.h(566): warning C4319:
	'~': zero extending 'unsigned long' to 'uint64_t' of greater size

To fix this, replace the "1UL" with RTE_BIT64 to force a 64-bit value
on all platforms.

Fixes: 64994b56cfd7 ("rcu: add RCU library supporting QSBR mechanism")
