Core mm expects __PAGETABLE_{PUD,PMD}_FOLDED to be defined if these page
table levels folded. Usually, these defines are provided by
<asm-generic/pgtable-nopmd.h> and <asm-generic/pgtable-nopud.h>.
But some architectures fold page table levels in a custom way. They
need to define these macros themself. This patch adds missing defines.
The patch fixes mm->nr_pmds underflow and eliminates dead __pmd_alloc()
and __pud_alloc() on architectures without these page table levels.
