Subject: [PATCH v9 01/13] x86/resctrl: Rename and move rdt files to new
directory
New generation of AMD processors start supporting RDT(or QOS)
features. Together these features will be called as RESCTRL.
With more than one vendors supporting these features, it seems
more appropriate to rename these files.
Create a new directory with the name 'resctrl' and move all the
intel_rdt files to the new directory. This way all the resctrl
related code resides inside one directory.
Suggested-by: Borislav Petkov <bp@...e.de>
