From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Subject: hexagon: remove __ARCH_USE_5LEVEL_HACK The hexagon architecture has 2 level page tables and as such most of the page table folding is already implemented in asm-generic/pgtable-nopmd.h. Fixup the only place in arch/hexagon to unfold the p4d level and remove __ARCH_USE_5LEVEL_HACK.
