* x86/resctrl: Bring cbm_validate() into the resource structureBabu Moger2018-11-223-9/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring all the functions that are different between the vendors into the resource structure and initialize them dynamically. Add _intel suffix to the Intel-specific functions. cbm_validate() which does cache bitmask validation, differs between the vendors as AMD allows non-contiguous masks. So, use separate functions for Intel and AMD.

* x86/resctrl: Initialize the vendor-specific resource functionsBabu Moger2018-11-223-9/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initialize the resource functions that are different between the vendors. Some features are initialized differently between the vendors. Add _intel suffix to Intel-specific functions. For example, the MBA feature varies significantly between Intel and AMD. Separate the initialization of these resource functions. That way we can easily add AMD's functions later.

* x86/resctrl: Rename and move rdt files to a separate directoryBabu Moger2018-11-228-0/+7326
New generation of AMD processors add support for RDT (or QOS) features. Together, these features will be called 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.
