patch 'kni: fix build with Linux 6.3' has been queued to stable release 21.11.5

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/25/23. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/b22ddfe63aec6ee9d178985d1e51973c489afe40

Thanks.

Kevin

Subject: [PATCH] kni: fix build with Linux 6.3

[ upstream commit 5f34cc454df420b9b2da8deb949fb76cba058b87 ]

KNI calls `get_user_pages_remote()` API which is using `FOLL_TOUCH`
flag, but `FOLL_TOUCH` is no more in public headers since v6.3,
causing a build error.

`FOLL_*` defines in Linux kernel first moved to another header [1],
later some of them moved to memory subsystem internal header [2] for 6.3

`get_user_pages_remote()` already sets `FOLL_TOUCH` internally,
no need to set this flag externally anyway, moving flag from the call
altogether.

[1]
Commit b5054174ac7c ("mm: move FOLL_* defs to mm_types.h")

[2]
Commit 2c2241081f7d ("mm/gup: move private gup FOLL_ flags to internal.h")

Fixes: e73831dc6c26 ("kni: support userspace VA")
