'has_legacy_ctx" means slightly different from 'is_legacy_ctx' in
original place. :-)
> + bool has_ppgtt;
similarly 'has_ppgtt' has different meaning from original
USE_FULL_PPGTT... from your purpose looks it is for indicating
whether a new ppgtt should be created here, then a clearer
name is required.

You abandoned 'global' from original name. Any reason?
