      x86: move prefill_possible_map calling early · 329513a3
      Yinghai Lu 提交于
      call it right after we are done with MADT/mptable handling, instead of
      doing that in setup_per_cpu_areas() later on...
      
      this way for_possible_cpu() can be used early.

      x86: cleanup early per cpu variables/accesses v4 · 23ca4bba
      Mike Travis 提交于
        * Introduce a new PER_CPU macro called "EARLY_PER_CPU".  This is
          used by some per_cpu variables that are initialized and accessed
          before there are per_cpu areas allocated.
      
          ["Early" in respect to per_cpu variables is "earlier than the per_cpu
          areas have been setup".]
      
          This patchset adds these new macros:
      
      	DEFINE_EARLY_PER_CPU(_type, _name, _initvalue)
      	EXPORT_EARLY_PER_CPU_SYMBOL(_name)
      	DECLARE_EARLY_PER_CPU(_type, _name)
      
      	early_per_cpu_ptr(_name)
      	early_per_cpu_map(_name, _idx)
      	early_per_cpu(_name, _cpu)
      
          The DEFINE macro defines the per_cpu variable as well as the early
          map and pointer.  It also initializes the per_cpu variable and map
          elements to "_initvalue".  The early_* macros provide access to
          the initial map (usually setup during system init) and the early
          pointer.  This pointer is initialized to point to the early map
          but is then NULL'ed when the actual per_cpu areas are setup.  After
          that the per_cpu variable is the correct access to the variable.
      
          The early_per_cpu() macro is not very efficient but does show how to
          access the variable if you have a function that can be called both
          "early" and "late".  It tests the early ptr to be NULL, and if not
          then it's still valid.  Otherwise, the per_cpu variable is used
          instead:
      
      	#define early_per_cpu(_name, _cpu) 			\
      		(early_per_cpu_ptr(_name) ?			\
      			early_per_cpu_ptr(_name)[_cpu] :	\
      			per_cpu(_name, _cpu))
      
          A better method is to actually check the pointer manually.  In the
          case below, numa_set_node can be called both "early" and "late":
      
      	void __cpuinit numa_set_node(int cpu, int node)
      	{
      	    int *cpu_to_node_map = early_per_cpu_ptr(x86_cpu_to_node_map);
      
      	    if (cpu_to_node_map)
      		    cpu_to_node_map[cpu] = node;
      	    else
      		    per_cpu(x86_cpu_to_node_map, cpu) = node;
      	}
      
        * Add a flag "arch_provides_topology_pointers" that indicates pointers
          to topology cpumask_t maps are available.  Otherwise, use the function
          returning the cpumask_t value.  This is useful if cpumask_t set size
          is very large to avoid copying data on to/off of the stack.
      
        * The coverage of CONFIG_DEBUG_PER_CPU_MAPS has been increased while
          the non-debug case has been optimized a bit.
      
        * Remove an unreferenced compiler warning in drivers/base/topology.c
      
        * Clean up #ifdef in setup.c
      
      For inclusion into sched-devel/latest tree.
