      Description

      This would have two potential benefits:

      • The page size could be reduced by half for intel and still return pages to the operating system in huge multiples. This would reduce the pathological cost of the scanning allocator.
      • It would mean that the current page size for power8 would be returned to the operating system. (Currently it is not because the huge pages are larger than 32 * 256K).
