## Description

In the Linux kernel, the following vulnerability has been resolved:  drm/xe: Reject page faults from non-fault-mode scratch VMs  Having scratch enabled does not make a VM capable of handling recoverable page faults. Allowing scratch VMs through the ASID lookup also admits dma-fence mode VMs.  If such a VM faults on an already valid VMA, the handler reports success without fixing the fault, causing the GPU to retry indefinitely.  Only allow fault-mode VMs through the ASID lookup. Fault-mode VMs using scratch remain supported, while faults from 3D VMs are rejected.  (cherry picked from commit bfb24a06405b652d37831f3fb66b71d33a6605de)
