The full diff-report can be found on Gist.

All changes to the kernels config for 5.15 are related to bumping the number of CPUs that can be handled by the kernels. This is done by AL in order to enable environments with more than the previously set 512 possible CPUs (e.g. the new high-memory instance types announced at re:invent with 896 vCPUs).

Those are some beefy machines indeed! Changes look good to me. Alas, AL has not yet put out a new 6.1 kernel.
