[Fix]
Apply the attached fix.
[How to test]
Install (and build) the patched packet.
[Regression potential]
The fix is composed of two patches:
1) the first patch simply garbage collect a reference to a function
that was never used but that had the API changed in Linux 6.5 - so,
it's a trivial change.
2) the second patch actually reimplement part of the vma scanning that was
removed in __get_user_pages_locked() in upstream commit
b2cac248191b7466c5819e0da617b0705a26e197 "mm/gup: removed vmas
array from internal GUP functions" - here is where most likely any regression
could be found.
