      This reverts commit e5a2c899.
      	Commit e5a2c899
       introduced an alternative_call, arch_fast_hash2,
      that selects between __jhash2 and __intel_crc4_2_hash based on the
      	Unfortunately, the alternative_call system does not appear to be
      suitable for use with C functions, as register usage is not handled
      properly for the called functions.  The __jhash2 function in particular
      clobbers registers that are not preserved when called via
      alternative_call, resulting in a panic for direct callers of
      arch_fast_hash2 on older CPUs lacking sse4_2.  It is possible that
      __intel_crc4_2_hash works merely by chance because it uses fewer

      mem-hotplug: reset node present pages when hot-adding a new pgdat · 0bd85420
      Tang Chen authored
      When memory is hot-added, all the memory is in offline state.  So clear
      all zones' present_pages because they will be updated in online_pages()
      and offline_pages().  Otherwise, /proc/zoneinfo will corrupt:
      When the memory of node2 is offline:
        # cat /proc/zoneinfo
        Node 2, zone   Movable
              spanned  8388608
              present  8388608
              managed  0
      When we online memory on node2:
        # cat /proc/zoneinfo
        Node 2, zone   Movable
              spanned  8388608
              present  16777216

      mem-hotplug: reset node managed pages when hot-adding a new pgdat · f784a3f1
      Tang Chen authored
      In free_area_init_core(), zone->managed_pages is set to an approximate
      value for lowmem, and will be adjusted when the bootmem allocator frees
      pages into the buddy system.
      But free_area_init_core() is also called by hotadd_new_pgdat() when
      hot-adding memory.  As a result, zone->managed_pages of the newly added
      node's pgdat is set to an approximate value in the very beginning.
      Even if the memory on that node has node been onlined,
      /sys/device/system/node/nodeXXX/meminfo has wrong value:
        hot-add node2 (memory not onlined)
        cat /sys/device/system/node/node2/meminfo
        Node 2 MemTotal:       33554432 kB
        Node 2 MemFree:               0 kB
        Node 2 MemUsed:        33554432 kB
        Node 2 Active:                0 kB
      This patch fixes this problem by reset node managed pages to 0 after
      hot-adding a new node.
      1. Move reset_managed_pages_done from reset_node_managed_pages() to
      2. Make reset_node_managed_pages() non-static
      3. Call reset_node_managed_pages() in hotadd_new_pgdat() after pgdat
         is initialized
