During the RFC it was agreed that "resctrl" will be the neutral name and
"intel_rdt", "amd_qos", or "arm mpam" would be the vendor specific names.

It is ok to delay that renaming but I think any renaming done from this
point should respect this agreement.

For example, if you want to rename intel_rdt.c then please rename it to
resctrl.c instead of just rdt.c which does not represent a generic name
as expressed as a goal in the subject of this patch.
