[PATCH 4/8] x86/mm: Add sync_global_pgds() for configuration with 5-level paging

This basically restores slightly modified version of original sync_global_pgds() which we had before folded p4d was introduced. The only modification is protection against 'address' overflow. Signed-off-by: Kirill A. Shutemov --- arch/x86/mm/init_64.c | 35
