Subject: kni: fix build with Linux 6.3
Patch-mainline: yes
Git-commit: 5f34cc454df420b9b2da8deb949fb76cba058b87
References: kernel 6.3
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.

Subject: kni: fix build with Linux 6.5
Git-repo: https://dpdk.org/git/dpdk
Git-commit: dd33d53b9a032d7376aa04a28a1235338e1fd78f
Patch-mainline: yes
References: kernel 6.5
The get_user_pages_remote() API has been modified in Linux kernel v6.5
[1], "struct vm_area_struct **vmas" parameter removed from the API.
To fix KNI build with Linux kernel v6.5, version check added around the
get_user_pages_remote() API.
