      [PATCH] node hotplug: register cpu: remove node struct · 76b67ed9
      KAMEZAWA Hiroyuki authored
      With Goto-san's patch, we can add new pgdat/node at runtime.  I'm now
      considering node-hot-add with cpu + memory on ACPI.
      
      I found acpi container, which describes node, could evaluate cpu before
      memory. This means cpu-hot-add occurs before memory hot add.
      
      In most part, cpu-hot-add doesn't depend on node hot add.  But register_cpu(),
      which creates symbolic link from node to cpu, requires that node should be
      onlined before register_cpu().  When a node is onlined, its pgdat should be
      there.
      
      This patch-set holds off creating symbolic link from node to cpu
      until node is onlined.
      
      This removes node arguments from register_cpu().
      
      Now, register_cpu() requires 'struct node' as its argument.  But the array of
      struct node is now unified in driver/base/node.c now (By Goto's node hotplug
      patch).  We can get struct node in generic way.  So, this argument is not
      necessary now.
      
      This patch also guarantees add cpu under node only when node is onlined.  It
      is necessary for node-hot-add vs.  cpu-hot-add patch following this.
      
      Moreover, register_cpu calculates cpu->node_id by cpu_to_node() without regard
      to its 'struct node *root' argument.  This patch removes it.
      
      Also modify callers of register_cpu()/unregister_cpu, whose args are changed
      by register-cpu-remove-node-struct patch.

      [PATCH] Register sysfs file for hotplugged new node · 0fc44159
      Yasunori Goto authored
      When new node becomes enable by hot-add, new sysfs file must be created for
      new node.  So, if new node is enabled by add_memory(), register_one_node() is
      called to create it.  In addition, I386's arch_register_node() and a part of
      register_nodes() of powerpc are consolidated to register_one_node() as a
      generic_code().
      
      This is tested by Tiger4(IPF) with node hot-plug emulation.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
