      x86: Fix UV BAU activation descriptor init · 0e2595cd
      Cliff Wickman 提交于
      The UV tlb shootdown code has a serious initialization error.
      
      An array of structures [32*8] is initialized as if it were [32].
      The array is indexed by (cpu number on the blade)*8, so the short
      initialization works for up to 4 cpus on a blade.
      But above that, we provide an invalid opcode to the hub's
      broadcast assist unit.
      
      This patch changes the allocation of the array to use its symbolic
      dimensions for better clarity. And initializes all 32*8 entries.
      
      Shortened 'UV_ACTIVATION_DESCRIPTOR_SIZE' to 'UV_ADP_SIZE' per Ingo's
      recommendation.
      
      Tested on the UV simulator.
