Two fixes:
mm/debug_vm_pgtable: remove pte entry from the page table
- remove a pte entry from the page table at the end of debug_vm_pgtable pte test
mm/page_table_check: check entries at pud and pmd levels
- check pmd and pud levels in page_table_check for regular entries not only for
huge pages when entries are replaced or cleared.
