This reverts commitbd72e28314. Reverted https://github.com/pytorch/pytorch/pull/128301 on behalf of https://github.com/huydhn due to Sorry for reverting your change but it fails XLA buildbd72e28314. Please rebase your PR before relanding because I think the failure is hidden by an unrelated broken trunk XLA failure from your current base commit ([comment](https://github.com/pytorch/pytorch/pull/128301#issuecomment-2169035822))
