Chunwei Chen 9829574834 ABD optimized page allocation code 
* Convert ABD to use the Linux Kernel scatterlist implementation
  instead of the hand rolled one from illumos.

* Scatter ABDs are preferentially populated with higher order
  compound pages from a single zone.  Allocation size is
  progressively decreased until it can be satisfied without
  performing reclaim or compaction.

* An alternate page allocator is provided for kernels older
  than 3.6 and for CONFIG_HIGHMEM systems.  This allocator
  is designed as a fallback for maximum compatibility.

* Extended abdstats to provide visibility in the the allocator.

* Add cached value for PAGESIZE in userspace.
