Skipped PRs:

• Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251: Semantically duplicates Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254; merge after Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254 conflicted only on formatting and **kwargs vs **_kwargs naming, then was aborted cleanly.

Failed PRs:

• None

Notes:

• Issue kwargs are not passed to loss calculation function. huggingface/transformers#43240 is closed as stale, but no equivalent fix was present on origin/main, so the open PRs still had merit.
• Fetched refs/pull/43254/head and refs/pull/43251/head from upstream into local mergeability refs.
• Merged Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254 with merge commit a988888.
• No unresolved conflicts or tracked working tree changes remain.
• Targeted Python validation could not run because torch is not installed in this environment.

Next steps:

• Keep Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254 as the cluster resolution.
• Do not also merge Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251 unless maintainers specifically prefer its **_kwargs spelling or formatting.
