In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Fix potential context UAFs
gem_context_register() makes the context visible to userspace, and which
point a separate thread can trigger the I915_GEM_CONTEXT_DESTROY ioctl.
So we need to ensure that nothing uses the ctx ptr after this. And we
need to ensure that adding the ctx to the xarray is the *last* thing
that gem_context_register() does with the ctx pointer.
[tursulin: Stable and fixes tags add/tidy.]
