These two patches were originally part of the XSM series that I have posted, and remain prerequisites for that series. However, they are independent of the XSM changes and are a useful simplification regardless of the use of XSM. The Acked-bys on these patches were provided before rebasing them over the copyback changes in 26268:1b72138bddda, which had minor conflicts that I resolved. [PATCH
