  Sub-NUMA clustering (SNC) invalidates previous assumptions of a 1:1
relationship between blades, sockets, and nodes.  Make changes
necessary to support this, including some general improvements along the
way.

Steve Wahl (8):
  x86/platform/uv: Add platform resolving #defines for misc
    GAM_MMIOH_REDIRECT*
  x86/platform/uv: Introduce helper function uv_pnode_to_socket.
  x86/platform/uv: Fix incorrect mask define use in calc_mmioh_map
  x86/platform/uv: When searching for minimums, start at INT_MAX not
    99999
  x86/platform/uv: helper functions for allocating and freeing
    conversion tables
  x86/platform/uv: UV support for sub-NUMA clustering
  x86/platform/uv: Remove remaining BUG_ON() and BUG() calls
  x86/platform/uv: Update UV[23] platform code for SNC
