      [PATCH] spin/rwlock init cleanups · 34af946a
      Ingo Molnar authored
      
      
      locking init cleanups:
      
       - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
       - convert rwlocks in a similar manner
      
      this patch was generated automatically.
      
      Motivation:
      
       - cleanliness
       - lockdep needs control of lock initialization, which the open-coded
         variants do not give
       - it's also useful for -rt and for lock debugging in general

      [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.
