Darrick J. Wong e5b46c7589 xfs: speed up xfarray sort by sorting xfile page contents directly 
If all the records in an xfarray subset live within the same memory
page, we can short-circuit even more quicksort recursion by mapping that
page into the local CPU and using the kernel's heapsort function to sort
the subset.  On the author's computer, this reduces the runtime by
another 15% on a 500,000 element array.
