[SRU][P:linux][PATCH v2 0/3] drm/xe: Lite restore breaks fdinfo drm-cycles-rcs reporting

[Thibault Ferrante]

BugLink: https://bugs.launchpad.net/bugs/2119526

[ Impact ]

 * GPU usage reported wrongly.
 * Upstream bug report: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/4532

[ Fix ]

 * Upstream fixes:
617d824c53 drm/xe: Add WA BB to capture active context utilization
9c7632faad drm/xe/lrc: Use a temporary buffer for WA BB
741d3ef8b8 drm/xe: Save the gt pointer in lrc and drop the tile

[ Test Plan ]

 * Trigger 100% usage of GPU, check for usage.

[ Where problems could occur ]

 * Regression in drm/xe driver and GPU management.

[ Other Info ]

 * Tested and submitted by intel.
 * Upstream fix afcad9241177 'drm/xe: Make WA BB part of LRC BO' skipped as deemed not usefull by intel further testing.

v2:
 - Switch 617d824c5 to backport (There is only context changes, but seems it can't be solved automatically).
 - Mention upstream fix.
