When adding hugetlb pages to the pool, we first create a list of the allocated pages before adding to the pool. Pass this list of pages to a new routine hugetlb_vmemmap_optimize_folios() for vmemmap optimization. We also modify the routine vmemmap_should_optimize() to check for pages that are already optimized. There are code paths that might request vmemmap optimization twice and we want to make sure this is not attempted. Signed-off-by: Mike Kravetz <mike.kravetz@xxxxxxxxxx>
