  x86/resctrl: Update documentation with Sub-NUMA cluster changes (2024-07-02 20:03:19 +0200)

----------------------------------------------------------------
 - Enable Sub-NUMA clustering to work with resource control on Intel by
   teaching resctrl to handle scopes due to the clustering which
   partitions the L3 cache into sets. Modify and extend the subsystem to
   handle such scopes properly

----------------------------------------------------------------
Tony Luck (19):
      x86/resctrl: Prepare for new domain scope
      x86/resctrl: Prepare to split rdt_domain structure
      x86/resctrl: Prepare for different scope for control/monitor operations
      x86/resctrl: Split the rdt_domain and rdt_hw_domain structures
      x86/resctrl: Add node-scope to the options for feature scope
      x86/resctrl: Introduce snc_nodes_per_l3_cache
      x86/resctrl: Block use of mba_MBps mount option on Sub-NUMA Cluster (SNC) systems

      x86/resctrl: Make __mon_event_count() handle sum domains
      x86/resctrl: Enable shared RMID mode on Sub-NUMA Cluster (SNC) systems
      x86/resctrl: Detect Sub-NUMA Cluster (SNC) mode
