This is the start of the stable review cycle for the 6.8.2 release.
There are 715 patches in this series, all will be posted as a response
to this one. If anyone has any issues with these being applied, please
let me know.
Applying the patch to 6.8.1 quickly fails the build of a previously
working config with:

DESCEND objtool
INSTALL libsubcmd_headers
DESCEND bpf/resolve_btfids

Introduced by "libbpf-add-bpf_token_create-api.patch".
A quick search indicates that at least mainline commit 35f96de04127
aka "bpf: Introduce BPF token object" is missing (but does not apply),
likely others.
