Kirill A. Shutemov 8aa76875dc arm: define __PAGETABLE_PMD_FOLDED for !LPAE 
ARM uses custom implementation of PMD folding in 2-level page table case.
Generic code expects to see __PAGETABLE_PMD_FOLDED to be defined if PMD is
folded, but ARM doesn't do this.  Let's fix it.

Defining __PAGETABLE_PMD_FOLDED will drop out unused __pmd_alloc().  It
also fixes problems with recently-introduced pmd accounting on ARM without
LPAE.
