If you're going to repost with a pre-commit, it would be better to have all the pieces squashed into one. Also you could look into using graphite or SPR for managing dependent pull requests |

Apologies for the commit spam here, graphite seems a good option hereon. However all dependent patches have landed, the diff here is now up to date. |

Please submit an NFC cleanup patch that just removes unnecessary bitcasting, before adding support for new atomic operations.
