[PATCH V5 31/31] powerpc/mm: Add a _PAGE_PTE bit

For a pte entry we will have _PAGE_PTE set. Our pte page address have a minimum alignment requirement of HUGEPD_SHIFT_MASK + 1. We use the lower 7 bits to indicate hugepd. ie. For pmd and pgd we can find: 1) _PAGE_PTE set pte -> indicate PTE 2) bits [2..6] non zero -> indicate hugepd. They
