Title
drm/xe/rtp: Add RING_FORCE_TO_NONPRIV_DENY to OA whitelists
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/xe/rtp: Add RING_FORCE_TO_NONPRIV_DENY to OA whitelists Unconditionally whitelisting OA registers is a security violation. Set RING_FORCE_TO_NONPRIV_DENY bit in OA nonpriv slots, so that OA registers don't get whitelisted by default after probe, gt reset, resume and engine reset. (cherry picked from commit 90511bdcfda97211c01f1d945d4ea616578d8fca)
