Hi all, Here's a refresh of my devmap stuff, now including the end goal as well. Patches #1 to #3 are just a rebase of v2, and I hope are ready to be picked up in the mm tree (#1 is currently doing double-duty in Dan's subsection series as well). Patch #4 could either go via mm if Will and Catalin agree, or could go via arm64 with a small tweak to let it build (but otherwise do nothing) until it meets up with #3 again. Robin.
