    m68k: mm: use pgtable-nopXd instead of 4level-fixup · 60e50f34
    Mike Rapoport authored
    m68k has two or three levels of page tables and can use appropriate
    pgtable-nopXd and folding of the upper layers.
    
    Replace usage of include/asm-generic/4level-fixup.h and explicit
    definitions of __PAGETABLE_PxD_FOLDED in m68k with
    include/asm-generic/pgtable-nopmd.h for two-level configurations and
    with include/asm-generic/pgtable-nopud.h for three-lelve configurations
    and adjust page table manipulation macros and functions accordingly.
