Subject bumped to v4, the v3 lore link added, and a "Changes since v3"
section written for the respin: the toggle measurement and its
reversal, the check fixes, the resume re-check, the register rename,
the jc42 and Skylake-SP clarifications, and the clang W=1 warning the
kernel test robot reported, with its Reported-by and Closes tags.
A DRAFT banner stays at the top until the posting; the send artifacts
under patches/ are generated from this text with the banner stripped.
