Subject: [PATCH 02/12] arm: nommu: use pgtable-nopud instead of 4level-fixup

From: Mike Rapoport <rppt@...ux.ibm.com>

The generic nommu implementation of page table manipulation takes care of
folding of the upper levels and does not require fixups.

Simply replace of include/asm-generic/4level-fixup.h with
include/asm-generic/pgtable-nopud.h.
