In my feedback from v1 I mentioned that having the feature for
DRM_GPUVM_RESV_PROTECTED only is unfortunate and that I think that we could=
 get
rid of !DRM_GPUVM_RESV_PROTECTED entirely.

MSM and nouveau are the only users of !DRM_GPUVM_RESV_PROTECTED, and I ment=
ioned
in v1 that I'm happy to have a look at this after LPC. I.e. scanning the pa=
tch
titles of v2 only, this looked like it was referring to this.
