parisc 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 parisc with
include/asm-generic/pgtable-nopmd.h
From: Mike Rapoport
32-bit version of sparc has three-level page tables and can use
pgtable-nopud and folding of the upper layers.
Replace usage of include/asm-generic/4level-fixup.h with
include/asm-generic/pgtable-nopud.h and adjust page table manipulation
macros and functions accordingly
From: Mike Rapoport
c6x is a nommu architecture and does not require fixup for upper layers of
the page tables because it is already handled by the generic nommu
implementation.
Replace usage of include/asm-generic/4level-fixup.h with
include/asm-generic/pgtable-nopud.h
