  - Merge "Support memory fragmentation tuning"
  - Support memory fragmentation tuning
    
    In some high memory pressure scenarios, the memory shortage would make
    the high order pages hard to be allocated and also the page allocation
    would go to the synchronous frequently reclaim thanks to the default gap
    between min<->low<->high is too small to wake up the kswapd(asynchronous
    reclaim) earlier. The spec proposes a mechanism to fine-tune the sysctl
    memory parameters(min_free_kbytes/watermark_scale_factor) at runtime to
    improve the situation.
