commit 042c48b73699c47d84b6ace73036e5a31a0d4cfc upstream.
Having the exec queue snapshot inside a "GuC CT" section was always wrong. Commit c28fd6c358db ("drm/xe/devcoredump: Improve section headings and add tile info") tried to fix that bug, but with that also broke the mesa tool that parses the devcoredump, hence it was reverted in commit a53da2fb25a3 ("drm/xe: Revert some changes that break a mesa debug tool").
With the mesa tool also fixed, this can propagate as a fix on both kernel and userspace side to avoid unnecessary headache for a debug feature.
