Important omitted fixes

I am leaving out f858c2b2ca04 bpf: Fix calling global functions from BPF_PROG_TYPE_EXT programs out of this backport since it is dependent on not-so-small parts of Introduce unstable CT lookup helpers patchset. Given these are from 5.18 which is also planned for 9.2 I figured it will be easier to include this fix with that backport. If we really want this fix along with 5.17 backport we can use v1 of this patch instead which does not rely on resolve_prog_type().
