So there's this new merge commit in tip:x86/boot: 54f71aa90c84 Merge branch 'x86/urgent' into x86/boot, to merge dependent commit and fixes which brings this fix into x86/boot: a718833cb456 ("x86/boot/sev: Avoid shared GHCB page for early memory acceptance") thus 54f71aa90c84 should be a proper base the rest of the startup/ series, right?
