No problem. I still need to post v5 first, and then one or two remaining patches will need to receive reviews. I can commit the series after that, and then this series could be extended later. However, if you wouldn't want to wait that long with your series (which I find a reasonable desire), then please poke people to review your series quickly, and then commit it. If I can post my v5 such that it is rebased even on *your* series (not just the CpuS3DataDxe driver from Mike), that would be best. Thanks!
