And as I said, NAK to that approach. I'm not going to add a 
CPU_ACCESS_REALLY_REQUIRED flag in the kernel just because mesa has 
messed up it's use case.

We could agree on filtering that flag from userspace when BOs are 
created and/or map it to a CREATE_CPU_ACCESS_HINT flag. But I would 
rather want to avoid that as well.
